Best Answer

3x + 12 = -7x - 28

First, move all variables to one side and numbers to the other. There are several different ways to begin, but let's move the 12 by subtraction from both sides.

3x = -7x - 40 is the new equation. Next, move the -7x to the left by addition to both sides.

10x = -40

Divide both sides by 10

x = -4
