-6L=6x+3y
Swap sides so that all variable terms are on the left hand side.
\frac{-6L}{-6}=\frac{6x+3y}{-6}
Divide both sides by -6.
L=\frac{6x+3y}{-6}
Dividing by -6 undoes the multiplication by -6.
L=-\frac{y}{2}-x
Divide 6x+3y by -6.
6x=-6L-3y
Subtract 3y from both sides.
6x=-3y-6L
The equation is in standard form.
\frac{6x}{6}=\frac{-3y-6L}{6}
Divide both sides by 6.
x=\frac{-3y-6L}{6}
Dividing by 6 undoes the multiplication by 6.
x=-\frac{y}{2}-L
Divide -6L-3y by 6.
