18-6x=3y
Swap sides so that all variable terms are on the left hand side.
-6x=3y-18
Subtract 18 from both sides.
\frac{-6x}{-6}=\frac{3y-18}{-6}
Divide both sides by -6.
x=\frac{3y-18}{-6}
Dividing by -6 undoes the multiplication by -6.
x=-\frac{y}{2}+3
Divide -18+3y by -6.
3y=18-6x
The equation is in standard form.
\frac{3y}{3}=\frac{18-6x}{3}
Divide both sides by 3.
y=\frac{18-6x}{3}
Dividing by 3 undoes the multiplication by 3.
y=6-2x
Divide 18-6x by 3.
