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

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