Isolate x and solve to get -12.

Explanation:

In order to solve for x, we want to get x alone. In this case, we can subtract 18 from both sides in order to get the 3x alone:
3x = -36

Now to isolate x, we divide both sides by 3:
x = -12

3x+18 = -18

Subtract 18 from both sides, since you wanna isolate the x, which gets you

3x=-36

Divide both sides by 3 to get the value for one x.
