Solve for L
\left\{\begin{matrix}L=\frac{V}{2W}\text{, }&W\neq 0\\L\in \mathrm{R}\text{, }&V=0\text{ and }W=0\end{matrix}\right.
Solve for V
V=2LW

2WL=V
The equation is in standard form.
\frac{2WL}{2W}=\frac{V}{2W}
Divide both sides by 2W.
L=\frac{V}{2W}
Dividing by 2W undoes the multiplication by 2W.
V=2LW
Swap sides so that all variable terms are on the left hand side.
