-\frac{3}{2}x=y-4
Subtract 4 from both sides.
\frac{-\frac{3}{2}x}{-\frac{3}{2}}=\frac{y-4}{-\frac{3}{2}}
Divide both sides of the equation by -\frac{3}{2}, which is the same as multiplying both sides by the reciprocal of the fraction.
x=\frac{y-4}{-\frac{3}{2}}
Dividing by -\frac{3}{2} undoes the multiplication by -\frac{3}{2}.
x=\frac{8-2y}{3}
Divide y-4 by -\frac{3}{2} by multiplying y-4 by the reciprocal of -\frac{3}{2}.
y=-\frac{3}{2}x+4
Swap sides so that all variable terms are on the left hand side.
