-\frac{2}{3}x=y
Swap sides so that all variable terms are on the left hand side.
\frac{-\frac{2}{3}x}{-\frac{2}{3}}=\frac{y}{-\frac{2}{3}}
Divide both sides of the equation by -\frac{2}{3}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y}{-\frac{2}{3}}
Dividing by -\frac{2}{3} undoes the multiplication by -\frac{2}{3}.
x=-\frac{3y}{2}
Divide y by -\frac{2}{3} by multiplying y by the reciprocal of -\frac{2}{3}.
