9x=8-2y
Subtract 2y from both sides.
\frac{9x}{9}=\frac{8-2y}{9}
Divide both sides by 9.
x=\frac{8-2y}{9}
Dividing by 9 undoes the multiplication by 9.
2y=8-9x
Subtract 9x from both sides.
\frac{2y}{2}=\frac{8-9x}{2}
Divide both sides by 2.
y=\frac{8-9x}{2}
Dividing by 2 undoes the multiplication by 2.
y=-\frac{9x}{2}+4
Divide 8-9x by 2.
