y+4=-\frac{3}{2}x+3
Use the distributive property to multiply -\frac{3}{2} by x-2.
-\frac{3}{2}x+3=y+4
Swap sides so that all variable terms are on the left hand side.
-\frac{3}{2}x=y+4-3
Subtract 3 from both sides.
-\frac{3}{2}x=y+1
Subtract 3 from 4 to get 1.
\frac{-\frac{3}{2}x}{-\frac{3}{2}}=\frac{y+1}{-\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+1}{-\frac{3}{2}}
Dividing by -\frac{3}{2} undoes the multiplication by -\frac{3}{2}.
x=\frac{-2y-2}{3}
Divide y+1 by -\frac{3}{2} by multiplying y+1 by the reciprocal of -\frac{3}{2}.
y+4=-\frac{3}{2}x+3
Use the distributive property to multiply -\frac{3}{2} by x-2.
y=-\frac{3}{2}x+3-4
Subtract 4 from both sides.
y=-\frac{3}{2}x-1
Subtract 4 from 3 to get -1.
