n+3=9\times \frac{4}{3}
Multiply both sides by \frac{4}{3}, the reciprocal of \frac{3}{4}.
n+3=\frac{9\times 4}{3}
Express 9\times \frac{4}{3} as a single fraction.
n+3=\frac{36}{3}
Multiply 9 and 4 to get 36.
n+3=12
Divide 36 by 3 to get 12.
n=12-3
Subtract 3 from both sides.
n=9
Subtract 3 from 12 to get 9.
