Solve for x
\left\{\begin{matrix}\\x=z\text{, }&\text{unconditionally}\\x\in \mathrm{R}\text{, }&z=0\end{matrix}\right.
Solve for z

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