\frac{1}{3}V-80-\frac{1}{4}V=0
Subtract \frac{1}{4}V from both sides.
\frac{1}{12}V-80=0
Combine \frac{1}{3}V and -\frac{1}{4}V to get \frac{1}{12}V.
\frac{1}{12}V=80
Add 80 to both sides. Anything plus zero gives itself.
V=80\times 12
Multiply both sides by 12, the reciprocal of \frac{1}{12}.
V=960
Multiply 80 and 12 to get 960.
