x=\frac{3}{4}-\frac{5}{4}
Subtract \frac{5}{4} from both sides.
x=\frac{3-5}{4}
Since \frac{3}{4} and \frac{5}{4} have the same denominator, subtract them by subtracting their numerators.
x=\frac{-2}{4}
Subtract 5 from 3 to get -2.
x=-\frac{1}{2}
Reduce the fraction \frac{-2}{4} to lowest terms by extracting and canceling out 2.
