5x=9-18y
Subtract 18y from both sides.
\frac{5x}{5}=\frac{9-18y}{5}
Divide both sides by 5.
x=\frac{9-18y}{5}
Dividing by 5 undoes the multiplication by 5.
18y=9-5x
Subtract 5x from both sides.
\frac{18y}{18}=\frac{9-5x}{18}
Divide both sides by 18.
y=\frac{9-5x}{18}
Dividing by 18 undoes the multiplication by 18.
y=-\frac{5x}{18}+\frac{1}{2}
Divide 9-5x by 18.
