-3x+5y-2x=3y
Subtract 2x from both sides.
-5x+5y=3y
Combine -3x and -2x to get -5x.
-5x=3y-5y
Subtract 5y from both sides.
-5x=-2y
Combine 3y and -5y to get -2y.
\frac{-5x}{-5}=-\frac{2y}{-5}
Divide both sides by -5.
x=-\frac{2y}{-5}
Dividing by -5 undoes the multiplication by -5.
x=\frac{2y}{5}
Divide -2y by -5.
-3x+5y-3y=2x
Subtract 3y from both sides.
-3x+2y=2x
Combine 5y and -3y to get 2y.
2y=2x+3x
Add 3x to both sides.
2y=5x
Combine 2x and 3x to get 5x.
\frac{2y}{2}=\frac{5x}{2}
Divide both sides by 2.
y=\frac{5x}{2}
Dividing by 2 undoes the multiplication by 2.
