\frac{1}{3}x-2-x=0
Subtract x from both sides.
-\frac{2}{3}x-2=0
Combine \frac{1}{3}x and -x to get -\frac{2}{3}x.
-\frac{2}{3}x=2
Add 2 to both sides. Anything plus zero gives itself.
x=2\left(-\frac{3}{2}\right)
Multiply both sides by -\frac{3}{2}, the reciprocal of -\frac{2}{3}.
x=-3
Cancel out 2 and 2.
