\frac{1}{4}x+\frac{1}{2}\left(150-x\right)=50
Reduce the fraction \frac{50}{100} to lowest terms by extracting and canceling out 50.
\frac{1}{4}x+\frac{1}{2}\times 150+\frac{1}{2}\left(-1\right)x=50
Use the distributive property to multiply \frac{1}{2} by 150-x.
\frac{1}{4}x+\frac{150}{2}+\frac{1}{2}\left(-1\right)x=50
Multiply \frac{1}{2} and 150 to get \frac{150}{2}.
\frac{1}{4}x+75+\frac{1}{2}\left(-1\right)x=50
Divide 150 by 2 to get 75.
\frac{1}{4}x+75-\frac{1}{2}x=50
Multiply \frac{1}{2} and -1 to get -\frac{1}{2}.
-\frac{1}{4}x+75=50
Combine \frac{1}{4}x and -\frac{1}{2}x to get -\frac{1}{4}x.
-\frac{1}{4}x=50-75
Subtract 75 from both sides.
-\frac{1}{4}x=-25
Subtract 75 from 50 to get -25.
x=-25\left(-4\right)
Multiply both sides by -4, the reciprocal of -\frac{1}{4}.
x=100
Multiply -25 and -4 to get 100.
