1. First distribute to get rid of the parentheses.

6x-12+3x-6=18

Combine like terms and isolate x to one side to solve for x.

9x=36

X=4, or C

2. Distribute to get rid of parentheses.

3x+12-4x-12=7x+16

Combine like terms and isolate x.

-x=7x+16

Move all x terms to one side and solve for x.

-8x+16

X=-2, A
