-x+3y=20-4x
Multiply both sides of the equation by 2.
-x+3y+4x=20
Add 4x to both sides.
-x+4x=20-3y
Subtract 3y from both sides.
3x=20-3y
Combine -x and 4x to get 3x.
\frac{3x}{3}=\frac{20-3y}{3}
Divide both sides by 3.
x=\frac{20-3y}{3}
Dividing by 3 undoes the multiplication by 3.
x=\frac{20}{3}-y
Divide 20-3y by 3.
-x+3y=20-4x
Multiply both sides of the equation by 2.
3y=20-4x+x
Add x to both sides.
3y=20-3x
Combine -4x and x to get -3x.
\frac{3y}{3}=\frac{20-3x}{3}
Divide both sides by 3.
y=\frac{20-3x}{3}
Dividing by 3 undoes the multiplication by 3.
y=\frac{20}{3}-x
Divide -3x+20 by 3.
