x-39-\frac{3}{4}x=0
Subtract \frac{3}{4}x from both sides.
\frac{1}{4}x-39=0
Combine x and -\frac{3}{4}x to get \frac{1}{4}x.
\frac{1}{4}x=39
Add 39 to both sides. Anything plus zero gives itself.
x=39\times 4
Multiply both sides by 4, the reciprocal of \frac{1}{4}.
x=156
Multiply 39 and 4 to get 156.
