Solve for h
\left\{\begin{matrix}h=\frac{3K}{h_{V}}\text{, }&h_{V}\neq 0\\h\in \mathrm{R}\text{, }&K=0\text{ and }h_{V}=0\end{matrix}\right.
Solve for K
K=\frac{hh_{V}}{3}

\frac{1}{3}h_{V}h=K
Swap sides so that all variable terms are on the left hand side.
\frac{h_{V}}{3}h=K
The equation is in standard form.
\frac{3\times \frac{h_{V}}{3}h}{h_{V}}=\frac{3K}{h_{V}}
Divide both sides by \frac{1}{3}h_{V}.
h=\frac{3K}{h_{V}}
Dividing by \frac{1}{3}h_{V} undoes the multiplication by \frac{1}{3}h_{V}.
