2x=39-9y
Subtract 9y from both sides.
\frac{2x}{2}=\frac{39-9y}{2}
Divide both sides by 2.
x=\frac{39-9y}{2}
Dividing by 2 undoes the multiplication by 2.
9y=39-2x
Subtract 2x from both sides.
\frac{9y}{9}=\frac{39-2x}{9}
Divide both sides by 9.
y=\frac{39-2x}{9}
Dividing by 9 undoes the multiplication by 9.
y=-\frac{2x}{9}+\frac{13}{3}
Divide 39-2x by 9.
