Solve for x (complex solution)
\left\{\begin{matrix}x=\frac{h}{\phi }\text{, }&\phi \neq 0\\x\in \mathrm{C}\text{, }&h=0\text{ and }\phi =0\end{matrix}\right.
Solve for x
\left\{\begin{matrix}x=\frac{h}{\phi }\text{, }&\phi \neq 0\\x\in \mathrm{R}\text{, }&h=0\text{ and }\phi =0\end{matrix}\right.
Solve for h
h=x\phi

\phi x=h
Swap sides so that all variable terms are on the left hand side.
\frac{\phi x}{\phi }=\frac{h}{\phi }
Divide both sides by \phi .
x=\frac{h}{\phi }
Dividing by \phi undoes the multiplication by \phi .
