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