    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
