We're going to break it down step by step, making sure everyone understands how to solve this equation. Think of it like a puzzle – we're just rearranging the pieces to find the value of 'b'. This article will walk you through each stage, providing explanations and tips to make sure you get it. Whether you're a student struggling with algebra or just someone curious about how these equations work, you've come to the right place. We'll start with the basics, simplify the expression, isolate the variable, and finally, find the solution. Ready? Let's get started!

Understanding the Basics: What are Equations?

So, before we jump into solving 7b - 6b + 29 = 374, let's quickly recap what an equation actually is. An equation is simply a mathematical statement that asserts the equality of two expressions. It's like a balanced scale; whatever you do to one side, you have to do the same to the other to keep it balanced. In our case, the equation 7b - 6b + 29 = 374 tells us that the expression on the left-hand side (LHS) is equal to the number on the right-hand side (RHS). Our main goal is to find the value of the variable, which in this case is 'b', that makes this statement true. Variables are like placeholders for numbers, and solving the equation means figuring out which number 'b' represents. It’s important to understand the concept of variables, constants, and the equal sign. The equation is a way of comparing the two sides of an expression to find a value that makes the expression valid. In this case, we're trying to figure out what the value of b is. Make sure you're aware of the order of operations, so you know how to operate on each term.

Before you start, you should have a solid grasp on basic arithmetic operations. This includes addition, subtraction, multiplication, and division. Without a good base, it can be pretty hard to keep up. Also, remember the commutative and associative properties of addition and multiplication. These properties let us rearrange terms to make our calculations easier. Understanding this can help you simplify the equation before isolating the variable. For example, knowing that 7b - 6b is the same as (7 - 6)b will help you simplify your first step. Keep in mind that we're trying to isolate the variable b. This means getting 'b' by itself on one side of the equation. We’ll achieve this by performing operations that balance the equation while also getting closer to the solution. The whole point is to keep the balance of the equation. Any action performed on one side must be performed on the other to preserve the equality.

Simplifying the Left-Hand Side (LHS)

Alright, let's get down to business and start simplifying our equation: 7b - 6b + 29 = 374. The first thing we need to do is simplify the left-hand side (LHS) of the equation. We can see that there are two terms with the variable 'b': 7b and -6b. We can combine these terms because they are like terms. Think of it this way: if you have 7 apples and you take away 6 apples, how many apples do you have left? You’d have 1 apple. So, 7b - 6b is the same as 1b, or simply 'b'.

Now, let's rewrite the equation with this simplification: b + 29 = 374. See how much cleaner that looks? We've successfully reduced the number of terms on the LHS. This is the first step to isolate the variable 'b'. Keep in mind that the simplification of the expression has not changed the validity of the equation. We have just made the equation simpler to read. The terms 7b and -6b are similar since they both contain the variable 'b'. You can add or subtract these terms to get a single term.

Think about the coefficients of the terms with the variable 'b' to help with the calculation. The coefficient is the number that is multiplied by the variable. In 7b, the coefficient is 7. In -6b, the coefficient is -6. Subtracting the coefficients (7 - 6) gives us 1. So we’re left with 1b, or just 'b'. Always remember to keep the equation balanced. The equation is valid as long as we make the same changes on both sides. This is an important rule to remember as you progress. Make sure you don’t skip steps or make mistakes in your calculations. If you're a bit rusty on your arithmetic, it's a good idea to refresh your skills. Accuracy is key when solving equations.

Isolating the Variable 'b'

Now that we've simplified the LHS, our next step is to isolate the variable 'b'. Our simplified equation is now b + 29 = 374. To isolate 'b', we need to get rid of the '+ 29' on the LHS. How do we do that? We use the inverse operation. The inverse of addition is subtraction. So, we're going to subtract 29 from both sides of the equation. Remember, what you do to one side, you must do to the other to keep the equation balanced.

So, let’s perform the subtraction:

b + 29 - 29 = 374 - 29

The '+ 29' and '- 29' on the LHS cancel each other out, leaving us with just 'b'. On the RHS, we subtract 29 from 374, which gives us 345. Therefore, our equation now looks like this: b = 345. Congratulations, guys! We've isolated the variable 'b'. It's now equal to 345. To do this, we used the principle of equality, which states that performing the same operation on both sides of the equation maintains the equality.

Think of it as removing the excess from one side to get the variable alone. It's like peeling an onion; you remove layers until you reach the core. In this case, the core is our variable, and each step removes something attached to it. Remember, always double-check your calculations, especially the subtraction. Simple arithmetic errors can lead to the wrong answer. Take your time, and don’t rush the process. Always make sure to write down each step carefully. This will help you find any errors if you get the wrong answer. Write down each step in a clear manner. It makes it easier to track your progress and avoid mistakes. If you find yourself struggling, break the equation down into smaller steps. It will make the process less overwhelming.

Finding the Solution and Checking Your Work

We've isolated the variable 'b', and we've found our answer: b = 345. But are we sure it's correct? It's always a good idea to check your work. This is the final step to make sure our solution is correct. To check our answer, we substitute the value of 'b' (which is 345) back into the original equation: 7b - 6b + 29 = 374.

So, we replace 'b' with 345:

7(345) - 6(345) + 29 = 374

Now, let's do the math:

2415 - 2070 + 29 = 374

345 + 29 = 374

374 = 374

See? The equation holds true! Since both sides of the equation are equal, our solution is correct. The final result helps us ensure we didn't make a mistake along the way. Checking your work is an essential skill in mathematics because it allows you to identify errors and build your confidence in solving problems. It's also a great way to reinforce your understanding of the concepts. Keep in mind that solving the equation and checking the answer helps build confidence and ensures accuracy.

Always double-check your work to be sure of the answer. It's a quick way to ensure you're on the right track. Remember, practice makes perfect! The more you practice solving equations, the more comfortable and confident you'll become. Make sure you practice similar problems to strengthen your grasp of the concepts and boost your problem-solving skills.
