23x=80-17y
Subtract 17y from both sides.
\frac{23x}{23}=\frac{80-17y}{23}
Divide both sides by 23.
x=\frac{80-17y}{23}
Dividing by 23 undoes the multiplication by 23.
17y=80-23x
Subtract 23x from both sides.
\frac{17y}{17}=\frac{80-23x}{17}
Divide both sides by 17.
y=\frac{80-23x}{17}
Dividing by 17 undoes the multiplication by 17.
