-3x=4y-20
Swap sides so that all variable terms are on the left hand side.
\frac{-3x}{-3}=\frac{4y-20}{-3}
Divide both sides by -3.
x=\frac{4y-20}{-3}
Dividing by -3 undoes the multiplication by -3.
x=\frac{20-4y}{3}
Divide -20+4y by -3.
4y=-3x+20
Add 20 to both sides.
4y=20-3x
The equation is in standard form.
\frac{4y}{4}=\frac{20-3x}{4}
Divide both sides by 4.
y=\frac{20-3x}{4}
Dividing by 4 undoes the multiplication by 4.
y=-\frac{3x}{4}+5
Divide -3x+20 by 4.
