39x+y=59
Swap sides so that all variable terms are on the left hand side.
39x=59-y
Subtract y from both sides.
\frac{39x}{39}=\frac{59-y}{39}
Divide both sides by 39.
x=\frac{59-y}{39}
Dividing by 39 undoes the multiplication by 39.
39x+y=59
Swap sides so that all variable terms are on the left hand side.
y=59-39x
Subtract 39x from both sides.
