\frac{1}{2}\left(165-x\right)+\frac{1}{4}x=50
Reduce the fraction \frac{50}{100} to lowest terms by extracting and canceling out 50.
\frac{1}{2}\times 165+\frac{1}{2}\left(-1\right)x+\frac{1}{4}x=50
Use the distributive property to multiply \frac{1}{2} by 165-x.
\frac{165}{2}+\frac{1}{2}\left(-1\right)x+\frac{1}{4}x=50
Multiply \frac{1}{2} and 165 to get \frac{165}{2}.
\frac{165}{2}-\frac{1}{2}x+\frac{1}{4}x=50
Multiply \frac{1}{2} and -1 to get -\frac{1}{2}.
\frac{165}{2}-\frac{1}{4}x=50
Combine -\frac{1}{2}x and \frac{1}{4}x to get -\frac{1}{4}x.
-\frac{1}{4}x=50-\frac{165}{2}
Subtract \frac{165}{2} from both sides.
-\frac{1}{4}x=\frac{100}{2}-\frac{165}{2}
Convert 50 to fraction \frac{100}{2}.
-\frac{1}{4}x=\frac{100-165}{2}
Since \frac{100}{2} and \frac{165}{2} have the same denominator, subtract them by subtracting their numerators.
-\frac{1}{4}x=-\frac{65}{2}
Subtract 165 from 100 to get -65.
x=-\frac{65}{2}\left(-4\right)
Multiply both sides by -4, the reciprocal of -\frac{1}{4}.
x=\frac{-65\left(-4\right)}{2}
Express -\frac{65}{2}\left(-4\right) as a single fraction.
x=\frac{260}{2}
Multiply -65 and -4 to get 260.
x=130
Divide 260 by 2 to get 130.
