300x+y=39000
Swap sides so that all variable terms are on the left hand side.
300x=39000-y
Subtract y from both sides.
\frac{300x}{300}=\frac{39000-y}{300}
Divide both sides by 300.
x=\frac{39000-y}{300}
Dividing by 300 undoes the multiplication by 300.
x=-\frac{y}{300}+130
Divide 39000-y by 300.
300x+y=39000
Swap sides so that all variable terms are on the left hand side.
y=39000-300x
Subtract 300x from both sides.
