x=50+\frac{x}{12}
Add 20 and 30 to get 50.
x-\frac{x}{12}=50
Subtract \frac{x}{12} from both sides.
\frac{11}{12}x=50
Combine x and -\frac{x}{12} to get \frac{11}{12}x.
x=50\times \frac{12}{11}
Multiply both sides by \frac{12}{11}, the reciprocal of \frac{11}{12}.
x=\frac{50\times 12}{11}
Express 50\times \frac{12}{11} as a single fraction.
x=\frac{600}{11}
Multiply 50 and 12 to get 600.
