30x=510-18y
Subtract 18y from both sides.
\frac{30x}{30}=\frac{510-18y}{30}
Divide both sides by 30.
x=\frac{510-18y}{30}
Dividing by 30 undoes the multiplication by 30.
x=-\frac{3y}{5}+17
Divide 510-18y by 30.
18y=510-30x
Subtract 30x from both sides.
\frac{18y}{18}=\frac{510-30x}{18}
Divide both sides by 18.
y=\frac{510-30x}{18}
Dividing by 18 undoes the multiplication by 18.
y=\frac{85-5x}{3}
Divide 510-30x by 18.
