600-x=\frac{3}{4}x
Reduce the fraction \frac{75}{100} to lowest terms by extracting and canceling out 25.
600-x-\frac{3}{4}x=0
Subtract \frac{3}{4}x from both sides.
600-\frac{7}{4}x=0
Combine -x and -\frac{3}{4}x to get -\frac{7}{4}x.
-\frac{7}{4}x=-600
Subtract 600 from both sides. Anything subtracted from zero gives its negation.
x=-600\left(-\frac{4}{7}\right)
Multiply both sides by -\frac{4}{7}, the reciprocal of -\frac{7}{4}.
x=\frac{-600\left(-4\right)}{7}
Express -600\left(-\frac{4}{7}\right) as a single fraction.
x=\frac{2400}{7}
Multiply -600 and -4 to get 2400.
