400x=57.9-20y
Subtract 20y from both sides.
\frac{400x}{400}=\frac{57.9-20y}{400}
Divide both sides by 400.
x=\frac{57.9-20y}{400}
Dividing by 400 undoes the multiplication by 400.
x=-\frac{y}{20}+\frac{579}{4000}
Divide 57.9-20y by 400.
20y=57.9-400x
Subtract 400x from both sides.
\frac{20y}{20}=\frac{57.9-400x}{20}
Divide both sides by 20.
y=\frac{57.9-400x}{20}
Dividing by 20 undoes the multiplication by 20.
y=\frac{579}{200}-20x
Divide 57.9-400x by 20.
