\frac{2}{3}x-7-\frac{1}{3}x=3
Subtract \frac{1}{3}x from both sides.
\frac{1}{3}x-7=3
Combine \frac{2}{3}x and -\frac{1}{3}x to get \frac{1}{3}x.
\frac{1}{3}x=3+7
Add 7 to both sides.
\frac{1}{3}x=10
Add 3 and 7 to get 10.
x=10\times 3
Multiply both sides by 3, the reciprocal of \frac{1}{3}.
x=30
Multiply 10 and 3 to get 30.
