1. Solve: 6(x - 2) + 3(x - 2) = 18
A. x = 2
B. x = 22/9
C. x = 4
2. Solve: 3(x + 4) - 4(x + 3) = 7x + 16.
A. x = -2
B. x = 3
C. x = 2

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
