25b=400-10m
Subtract 10m from both sides.
\frac{25b}{25}=\frac{400-10m}{25}
Divide both sides by 25.
b=\frac{400-10m}{25}
Dividing by 25 undoes the multiplication by 25.
b=-\frac{2m}{5}+16
Divide 400-10m by 25.
10m=400-25b
Subtract 25b from both sides.
\frac{10m}{10}=\frac{400-25b}{10}
Divide both sides by 10.
m=\frac{400-25b}{10}
Dividing by 10 undoes the multiplication by 10.
m=-\frac{5b}{2}+40
Divide 400-25b by 10.
