30m+20n=\frac{1080}{4}
Divide both sides by 4.
30m+20n=270
Divide 1080 by 4 to get 270.
30m=270-20n
Subtract 20n from both sides.
\frac{30m}{30}=\frac{270-20n}{30}
Divide both sides by 30.
m=\frac{270-20n}{30}
Dividing by 30 undoes the multiplication by 30.
m=-\frac{2n}{3}+9
Divide 270-20n by 30.
30m+20n=\frac{1080}{4}
Divide both sides by 4.
30m+20n=270
Divide 1080 by 4 to get 270.
20n=270-30m
Subtract 30m from both sides.
\frac{20n}{20}=\frac{270-30m}{20}
Divide both sides by 20.
n=\frac{270-30m}{20}
Dividing by 20 undoes the multiplication by 20.
n=\frac{27-3m}{2}
Divide 270-30m by 20.
