\frac{1}{2}x-7-\frac{1}{3}x=0
Subtract \frac{1}{3}x from both sides.
\frac{1}{6}x-7=0
Combine \frac{1}{2}x and -\frac{1}{3}x to get \frac{1}{6}x.
\frac{1}{6}x=7
Add 7 to both sides. Anything plus zero gives itself.
x=7\times 6
Multiply both sides by 6, the reciprocal of \frac{1}{6}.
x=42
Multiply 7 and 6 to get 42.
