9x=18-3y
Subtract 3y from both sides.
\frac{9x}{9}=\frac{18-3y}{9}
Divide both sides by 9.
x=\frac{18-3y}{9}
Dividing by 9 undoes the multiplication by 9.
x=-\frac{y}{3}+2
Divide 18-3y by 9.
3y=18-9x
Subtract 9x from both sides.
\frac{3y}{3}=\frac{18-9x}{3}
Divide both sides by 3.
y=\frac{18-9x}{3}
Dividing by 3 undoes the multiplication by 3.
y=6-3x
Divide 18-9x by 3.
