-x=3y
Swap sides so that all variable terms are on the left hand side.
\frac{-x}{-1}=\frac{3y}{-1}
Divide both sides by -1.
x=\frac{3y}{-1}
Dividing by -1 undoes the multiplication by -1.
x=-3y
Divide 3y by -1.
3y=-x
The equation is in standard form.
\frac{3y}{3}=-\frac{x}{3}
Divide both sides by 3.
y=-\frac{x}{3}
Dividing by 3 undoes the multiplication by 3.
