2x=8-3y
Subtract 3y from both sides.
\frac{2x}{2}=\frac{8-3y}{2}
Divide both sides by 2.
x=\frac{8-3y}{2}
Dividing by 2 undoes the multiplication by 2.
x=-\frac{3y}{2}+4
Divide 8-3y by 2.
3y=8-2x
Subtract 2x from both sides.
\frac{3y}{3}=\frac{8-2x}{3}
Divide both sides by 3.
y=\frac{8-2x}{3}
Dividing by 3 undoes the multiplication by 3.
