Solve r=4cn

$$r = 4 cn$$

Solve for c (complex solution)

$$\left\{\begin{matrix}c=\frac{r}{4n}\text{, }&n\neq 0\\c\in \mathrm{C}\text{, }&r=0\text{ and }n=0\end{matrix}\right.$$

Steps for Solving Linear Equation

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

$$4cn=r$$

The equation is in standard form.

$$4nc=r$$

Divide both sides by 4n.

$$\frac{4nc}{4n}=\frac{r}{4n}$$

Dividing by 4n undoes the multiplication by 4n.

$$c=\frac{r}{4n}$$

Solve for n (complex solution)

$$\left\{\begin{matrix}n=\frac{r}{4c}\text{, }&c\neq 0\\n\in \mathrm{C}\text{, }&r=0\text{ and }c=0\end{matrix}\right.$$

Steps for Solving Linear Equation

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

$$4cn=r$$

Divide both sides by 4c.

$$\frac{4cn}{4c}=\frac{r}{4c}$$

Dividing by 4c undoes the multiplication by 4c.

$$n=\frac{r}{4c}$$

Solve for c

$$\left\{\begin{matrix}c=\frac{r}{4n}\text{, }&n\neq 0\\c\in \mathrm{R}\text{, }&r=0\text{ and }n=0\end{matrix}\right.$$
