\frac{8}{9}n-n=\frac{1}{2}n
Divide 5 by 5 to get 1.
-\frac{1}{9}n=\frac{1}{2}n
Combine \frac{8}{9}n and -n to get -\frac{1}{9}n.
-\frac{1}{9}n-\frac{1}{2}n=0
Subtract \frac{1}{2}n from both sides.
-\frac{11}{18}n=0
Combine -\frac{1}{9}n and -\frac{1}{2}n to get -\frac{11}{18}n.
n=0
Product of two numbers is equal to 0 if at least one of them is 0. Since -\frac{11}{18} is not equal to 0, n must be equal to 0.
