2x-2y+30=y
Use the distributive property to multiply 2 by x-y.
2x+30=y+2y
Add 2y to both sides.
2x+30=3y
Combine y and 2y to get 3y.
2x=3y-30
Subtract 30 from both sides.
\frac{2x}{2}=\frac{3y-30}{2}
Divide both sides by 2.
x=\frac{3y-30}{2}
Dividing by 2 undoes the multiplication by 2.
x=\frac{3y}{2}-15
Divide -30+3y by 2.
2x-2y+30=y
Use the distributive property to multiply 2 by x-y.
2x-2y+30-y=0
Subtract y from both sides.
2x-3y+30=0
Combine -2y and -y to get -3y.
-3y+30=-2x
Subtract 2x from both sides. Anything subtracted from zero gives its negation.
-3y=-2x-30
Subtract 30 from both sides.
\frac{-3y}{-3}=\frac{-2x-30}{-3}
Divide both sides by -3.
y=\frac{-2x-30}{-3}
Dividing by -3 undoes the multiplication by -3.
y=\frac{2x}{3}+10
Divide -2x-30 by -3.
