-x=1-3y
Subtract 3y from both sides.
\frac{-x}{-1}=\frac{1-3y}{-1}
Divide both sides by -1.
x=\frac{1-3y}{-1}
Dividing by -1 undoes the multiplication by -1.
x=3y-1
Divide 1-3y by -1.
3y=1+x
Add x to both sides.
3y=x+1
The equation is in standard form.
\frac{3y}{3}=\frac{x+1}{3}
Divide both sides by 3.
y=\frac{x+1}{3}
Dividing by 3 undoes the multiplication by 3.
