Solve for I
\left\{\begin{matrix}I=\frac{P}{V}\text{, }&V\neq 0\\I\in \mathrm{R}\text{, }&P=0\text{ and }V=0\end{matrix}\right.
Solve for P
P=IV

IV=P
Swap sides so that all variable terms are on the left hand side.
VI=P
The equation is in standard form.
\frac{VI}{V}=\frac{P}{V}
Divide both sides by V.
I=\frac{P}{V}
Dividing by V undoes the multiplication by V.
