Solve for c
\left\{\begin{matrix}c=\frac{s}{h}\text{, }&h\neq 0\\c\in \mathrm{R}\text{, }&s=0\text{ and }h=0\end{matrix}\right.
Solve for h
\left\{\begin{matrix}h=\frac{s}{c}\text{, }&c\neq 0\\h\in \mathrm{R}\text{, }&s=0\text{ and }c=0\end{matrix}\right.

ch=s
Swap sides so that all variable terms are on the left hand side.
hc=s
The equation is in standard form.
\frac{hc}{h}=\frac{s}{h}
Divide both sides by h.
c=\frac{s}{h}
Dividing by h undoes the multiplication by h.
ch=s
Swap sides so that all variable terms are on the left hand side.
\frac{ch}{c}=\frac{s}{c}
Divide both sides by c.
h=\frac{s}{c}
Dividing by c undoes the multiplication by c.
