-50x=80-20y
Subtract 20y from both sides.
\frac{-50x}{-50}=\frac{80-20y}{-50}
Divide both sides by -50.
x=\frac{80-20y}{-50}
Dividing by -50 undoes the multiplication by -50.
x=\frac{2y-8}{5}
Divide 80-20y by -50.
20y=80+50x
Add 50x to both sides.
20y=50x+80
The equation is in standard form.
\frac{20y}{20}=\frac{50x+80}{20}
Divide both sides by 20.
y=\frac{50x+80}{20}
Dividing by 20 undoes the multiplication by 20.
y=\frac{5x}{2}+4
Divide 80+50x by 20.
