Step-by-step explanation:

Step 1: Define

-2/3a - 6 = 12

Step 2: Solve for a

  1. Add 6 to both sides:                      -2/3a = 18
  2. Divide -2/3 on both sides:             a = -27

Answer: a = -27

Step-by-step explanation:

-2/3a - 6 = 12

ADD 6 TO BOTH SIDES

-2/3a = 18

MULTIPLY BY 3 TO BOTH SIDES

-2a = 54

now you want to get the a by itself so DIVIDE BY -2

so... a=-27
