Question: 1 / 400

How do you simplify the expression 3(x + 2) + 4(x - 5)?

7x - 14

To simplify the expression 3(x + 2) + 4(x - 5), follow these steps:

First, distribute the terms within the parentheses. When applying the distributive property:

1. For the first part, 3(x + 2):

- Multiply 3 by both x and 2:

- 3 * x = 3x

- 3 * 2 = 6

- Therefore, this part simplifies to 3x + 6.

2. Next, for the second part, 4(x - 5):

- Multiply 4 by both x and -5:

- 4 * x = 4x

- 4 * -5 = -20

- This part simplifies to 4x - 20.

Now, combine both results:

- From the first part, you have 3x + 6.

- From the second part, you have 4x - 20.

Add these together:

3x + 6 + 4x - 20.

Combine like terms:

- Combine the x terms: 3x + 4x = 7x.

- Combine the constant terms: 6
