Solve for x
\left\{\begin{matrix}x=\frac{w}{yz}\text{, }&z\neq 0\text{ and }y\neq 0\\x\in \mathrm{R}\text{, }&\left(z=0\text{ or }y=0\right)\text{ and }w=0\end{matrix}\right.
Solve for w
w=xyz

xyz=w
Swap sides so that all variable terms are on the left hand side.
yzx=w
The equation is in standard form.
\frac{yzx}{yz}=\frac{w}{yz}
Divide both sides by yz.
x=\frac{w}{yz}
Dividing by yz undoes the multiplication by yz.
