3x - 2 = -20

To solve for the variable x, we have to make it by itself. First, add color(blue)2 to both sides of the equation:
3x - 2 quadcolor(blue)(+quad2) = -20 quadcolor(blue)(+quad2)

3x = -18

Now divide both sides by color(blue)3:
(3x)/color(blue)3 = -18/color(blue)3

Therefore,
x = -6

Hope this helps!
