Answer:

Step-by-step explanation:

1.Distribute

12x - 66 + 15 =21

2.Add the numbers

12x-51=21

3.Add 51 to both sides of the equation

12x -51 +51 = 21+51

4.Simplify

12x=72

5. Divide both sides of the equation by the same term

12x/12 = 72/12

6. Divide the numbers

x=6

And you have your answer x=6
