-12\left(-\frac{3}{4}\right)=b
Multiply both sides by -\frac{3}{4}, the reciprocal of -\frac{4}{3}.
\frac{-12\left(-3\right)}{4}=b
Express -12\left(-\frac{3}{4}\right) as a single fraction.
\frac{36}{4}=b
Multiply -12 and -3 to get 36.
9=b
Divide 36 by 4 to get 9.
b=9
Swap sides so that all variable terms are on the left hand side.
