\frac{1}{4}x-\frac{18}{100}x=7
Reduce the fraction \frac{25}{100} to lowest terms by extracting and canceling out 25.
\frac{1}{4}x-\frac{9}{50}x=7
Reduce the fraction \frac{18}{100} to lowest terms by extracting and canceling out 2.
\frac{7}{100}x=7
Combine \frac{1}{4}x and -\frac{9}{50}x to get \frac{7}{100}x.
x=7\times \frac{100}{7}
Multiply both sides by \frac{100}{7}, the reciprocal of \frac{7}{100}.
x=100
Cancel out 7 and 7.
