Solve for x
\left\{\begin{matrix}x=\frac{z^{2}-1}{y}\text{, }&y\neq 0\\x\in \mathrm{R}\text{, }&y=0\text{ and }|z|=1\end{matrix}\right.

yx=z^{2}-1
The equation is in standard form.
\frac{yx}{y}=\frac{z^{2}-1}{y}
Divide both sides by y.
x=\frac{z^{2}-1}{y}
Dividing by y undoes the multiplication by y.
