Question

3.

Diego is asked to solve 3x - 8 = 4(x + 5). What do you
recommend he does to each side first?

Answer 1

Right side

Explanation:

3x - 8 = 4(x + 5)

3x - 8 = 4x + 20

3x - 4x = 20 + 8

-x = 28 (divide both sides by -1)

x = -28

Answer 2

x=-36

Explanation:

I would start by distributing the right side first

4(x+5) is 4x+20.

That gives you 3x-8=4x+20

4x-3x=1x

-28-8= -36

x=-36
