Answer:

Explanation:

The error is in the second step. For some unknown reason, the x was dropped and the 3 was subtracted from the 7.

It should be

9x +3x + 12 = 7

12x + 12 = 7 Subtract 12 from both sides.

12x + 12 - 12 = 7 - 12 Combine

12x = -5 Divide by 12

12x/12 = -5/12

x = -5/12 or x = - 0.4167
