Explanation:
Add 2x to both sides
-3x=6
Divide both sides by-3
x=-2
_____
First you want to separate the variable terms and constant terms. Here, that is done by adding the opposite of -2x to both sides.
Then you want to divide by the coefficient of x, so you have the variable by itself. Since the coefficient after the first step is -3, you divide both sides by -3.
