-18-\frac{3}{4}x=3
Subtract 18 from 0 to get -18.
-\frac{3}{4}x=3+18
Add 18 to both sides.
-\frac{3}{4}x=21
Add 3 and 18 to get 21.
x=21\left(-\frac{4}{3}\right)
Multiply both sides by -\frac{4}{3}, the reciprocal of -\frac{3}{4}.
x=\frac{21\left(-4\right)}{3}
Express 21\left(-\frac{4}{3}\right) as a single fraction.
x=\frac{-84}{3}
Multiply 21 and -4 to get -84.
x=-28
Divide -84 by 3 to get -28.
