Solve y=operatorname{sel}x

$$y = \operatorname { sel } x$$

Solve for l (complex solution)

$$\left\{\begin{matrix}l=\frac{y}{esx}\text{, }&x\neq 0\text{ and }s\neq 0\\l\in \mathrm{C}\text{, }&\left(x=0\text{ or }s=0\right)\text{ and }y=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$selx=y$$

The equation is in standard form.

$$esxl=y$$

Divide both sides by sex.

$$\frac{esxl}{esx}=\frac{y}{esx}$$

Dividing by sex undoes the multiplication by sex.

$$l=\frac{y}{esx}$$

Solve for s (complex solution)

$$\left\{\begin{matrix}s=\frac{y}{elx}\text{, }&x\neq 0\text{ and }l\neq 0\\s\in \mathrm{C}\text{, }&\left(l=0\text{ or }x=0\right)\text{ and }y=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$selx=y$$

The equation is in standard form.

$$elxs=y$$

Divide both sides by elx.

$$\frac{elxs}{elx}=\frac{y}{elx}$$

Dividing by elx undoes the multiplication by elx.

$$s=\frac{y}{elx}$$

Solve for l

$$\left\{\begin{matrix}l=\frac{y}{esx}\text{, }&x\neq 0\text{ and }s\neq 0\\l\in \mathrm{R}\text{, }&\left(x=0\text{ or }s=0\right)\text{ and }y=0\end{matrix}\right.$$
