Solve for I
\left\{\begin{matrix}I=\frac{p}{8v}\text{, }&v\neq 0\\I\in \mathrm{R}\text{, }&p=0\text{ and }v=0\end{matrix}\right.
Solve for p
p=8Iv

240vI=30p
Swap sides so that all variable terms are on the left hand side.
\frac{240vI}{240v}=\frac{30p}{240v}
Divide both sides by 240v.
I=\frac{30p}{240v}
Dividing by 240v undoes the multiplication by 240v.
I=\frac{p}{8v}
Divide 30p by 240v.
30p=240Iv
The equation is in standard form.
\frac{30p}{30}=\frac{240Iv}{30}
Divide both sides by 30.
p=\frac{240Iv}{30}
Dividing by 30 undoes the multiplication by 30.
p=8Iv
Divide 240vI by 30.
