13+w-\frac{2}{3}w=16
Add -4 and 17 to get 13.
13+\frac{1}{3}w=16
Combine w and -\frac{2}{3}w to get \frac{1}{3}w.
\frac{1}{3}w=16-13
Subtract 13 from both sides.
\frac{1}{3}w=3
Subtract 13 from 16 to get 3.
w=3\times 3
Multiply both sides by 3, the reciprocal of \frac{1}{3}.
w=9
Multiply 3 and 3 to get 9.
