2(3^2)(8+3)

=2(9)(11)

=198

==============================

Column A

6z-5 if z=-2

6(-2)-5

=-12-5

=-17

Column B

-6z – 5 if z = 2

-6(2)-5

=-17

============================

Column A

The solution of

2(x-3) = 6x

2x-6 = 6x

4x=-6

x=-3/2

Column B

The solution of (note typo assumed)

3x + 2**=**5x + 6

2x=2-6

x=-4/2=-2
