5-\frac{2}{3}n-\frac{2}{3}\left(-3\right)=1
Use the distributive property to multiply -\frac{2}{3} by n-3.
5-\frac{2}{3}n+\frac{-2\left(-3\right)}{3}=1
Express -\frac{2}{3}\left(-3\right) as a single fraction.
5-\frac{2}{3}n+\frac{6}{3}=1
Multiply -2 and -3 to get 6.
5-\frac{2}{3}n+2=1
Divide 6 by 3 to get 2.
7-\frac{2}{3}n=1
Add 5 and 2 to get 7.
-\frac{2}{3}n=1-7
Subtract 7 from both sides.
-\frac{2}{3}n=-6
Subtract 7 from 1 to get -6.
n=-6\left(-\frac{3}{2}\right)
Multiply both sides by -\frac{3}{2}, the reciprocal of -\frac{2}{3}.
n=\frac{-6\left(-3\right)}{2}
Express -6\left(-\frac{3}{2}\right) as a single fraction.
n=\frac{18}{2}
Multiply -6 and -3 to get 18.
n=9
Divide 18 by 2 to get 9.
