-3x=2y
Combine 2x and -5x to get -3x.
\frac{-3x}{-3}=\frac{2y}{-3}
Divide both sides by -3.
x=\frac{2y}{-3}
Dividing by -3 undoes the multiplication by -3.
x=-\frac{2y}{3}
Divide 2y by -3.
-3x=2y
Combine 2x and -5x to get -3x.
2y=-3x
Swap sides so that all variable terms are on the left hand side.
\frac{2y}{2}=-\frac{3x}{2}
Divide both sides by 2.
y=-\frac{3x}{2}
Dividing by 2 undoes the multiplication by 2.
