Question

Simplify 3(x + 2) + 4(x - 5)
A. 7x - 3
B.7x - 14
C.7x + 26

Answer 1

7x - 14

Explanation:

3(x + 2) + 4(x - 5)

3x + 6 + 4x - 20

7x - 14

Answer 2

For this case we must simplify the following expression:

`3 (x + 2) +4 (x-5)`

Applying distributive property to the terms within the parenthesis we have:

`3x + 6 + 4x-20 =`

Adding similar terms:

`3x + 4x + 6-20 =`

Finally we have that the expression is reduced to:

`7x-14`

Answer:

`7x-14`
