9x+2=20-18y
Subtract 18y from both sides.
9x=20-18y-2
Subtract 2 from both sides.
9x=18-18y
Subtract 2 from 20 to get 18.
\frac{9x}{9}=\frac{18-18y}{9}
Divide both sides by 9.
x=\frac{18-18y}{9}
Dividing by 9 undoes the multiplication by 9.
x=2-2y
Divide 18-18y by 9.
18y+2=20-9x
Subtract 9x from both sides.
18y=20-9x-2
Subtract 2 from both sides.
18y=18-9x
Subtract 2 from 20 to get 18.
\frac{18y}{18}=\frac{18-9x}{18}
Divide both sides by 18.
y=\frac{18-9x}{18}
Dividing by 18 undoes the multiplication by 18.
y=-\frac{x}{2}+1
Divide 18-9x by 18.
