x+x\times \frac{1}{2}=400
Reduce the fraction \frac{50}{100} to lowest terms by extracting and canceling out 50.
\frac{3}{2}x=400
Combine x and x\times \frac{1}{2} to get \frac{3}{2}x.
x=400\times \frac{2}{3}
Multiply both sides by \frac{2}{3}, the reciprocal of \frac{3}{2}.
x=\frac{400\times 2}{3}
Express 400\times \frac{2}{3} as a single fraction.
x=\frac{800}{3}
Multiply 400 and 2 to get 800.
