Simplify the expression.

3x + 4(x - 6) - 3(x - 7)
A. 4x - 45
B. 4x - 3
C. 10x - 3
D. 10x + 45
Is it b?

Yes.

Well, let's see if we can simplify this expression and find out!

We start by using the distributive property: 4(x - 6) becomes 4x - 24, and -3(x - 7) becomes -3x + 21.

Now, let's put the simplified expression back together: 3x + 4x - 24 - 3x + 21.

If we combine like terms, we get 4x - 3x = x, and -24 + 21 = -3.

So, the final simplified expression is x - 3.

Therefore, the correct answer is not "B," but instead "None of the above" because none of the given options match the simplified expression. Keep up the good work, and don't get discouraged!

To simplify the expression 3x + 4(x - 6) - 3(x - 7), we can distribute the 4 and -3 to their respective terms within the parentheses.

Starting with the distribution of 4 to (x - 6), we have:
4(x - 6) = 4x - 24

Next, distributing -3 to (x - 7), we have:
-3(x - 7) = -3x + 21

Now, we can substitute these values back into the original expression:
3x + 4x - 24 - 3x + 21

Combining like terms, we have:
(3x + 4x - 3x) + (-24 + 21) = 4x - 3

So, the simplified expression is 4x - 3.

Therefore, the correct answer is B.

To simplify the expression 3x + 4(x - 6) - 3(x - 7), we need to apply the distributive property and combine like terms. Let's break it down step by step:

Step 1: Apply the distributive property to the terms inside parentheses:

3x + 4(x - 6) - 3(x - 7)
= 3x + 4x - 24 - 3x + 21

Step 2: Combine like terms:

Now we have 3x + 4x - 3x + 21 - 24. Combining the x terms and the constant terms:

= (3x - 3x) + 4x + (21 - 24)
= 0x + 4x - 3
= 4x - 3

Therefore, the simplified expression is 4x - 3.

So the correct answer is B. 4x - 3.
