5x=4-20y
Subtract 20y from both sides.
\frac{5x}{5}=\frac{4-20y}{5}
Divide both sides by 5.
x=\frac{4-20y}{5}
Dividing by 5 undoes the multiplication by 5.
x=\frac{4}{5}-4y
Divide 4-20y by 5.
20y=4-5x
Subtract 5x from both sides.
\frac{20y}{20}=\frac{4-5x}{20}
Divide both sides by 20.
y=\frac{4-5x}{20}
Dividing by 20 undoes the multiplication by 20.
y=-\frac{x}{4}+\frac{1}{5}
Divide 4-5x by 20.
