 9x + 2 = 3x - 10
<u>-3x        -3x         </u>
 6x + 2 = -10
<u>        -2     -2</u>
       <u>6x</u> = <u>-12</u>
        6       6
         x = -2

3(x - 2) = -2(x + 3)
3(x) - 3(2) = -2(x) - 2(3)
3x - 6 = -2x - 6
<u>+2x      +2x        </u>
5x - 6 = -6
<u>     +6    +6</u>
      <u>5x</u> =<u> 0</u>
       5     5
       x = 0
