y = \lim x
Solve for l
\left\{\begin{matrix}l=\frac{y}{Im(x)}\text{, }&Im(x)\neq 0\\l\in \mathrm{C}\text{, }&y=0\text{ and }Im(x)=0\end{matrix}\right.

lIm(x)=y
Swap sides so that all variable terms are on the left hand side.
Im(x)l=y
The equation is in standard form.
\frac{Im(x)l}{Im(x)}=\frac{y}{Im(x)}
Divide both sides by Im(x).
l=\frac{y}{Im(x)}
Dividing by Im(x) undoes the multiplication by Im(x).
