Solve r=3cm

$$r = 3 cm$$

Solve for c (complex solution)

$$\left\{\begin{matrix}c=\frac{r}{3m}\text{, }&m\neq 0\\c\in \mathrm{C}\text{, }&r=0\text{ and }m=0\end{matrix}\right.$$

Steps for Solving Linear Equation

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

$$3cm=r$$

The equation is in standard form.

$$3mc=r$$

Divide both sides by 3m.

$$\frac{3mc}{3m}=\frac{r}{3m}$$

Dividing by 3m undoes the multiplication by 3m.

$$c=\frac{r}{3m}$$

Solve for m (complex solution)

$$\left\{\begin{matrix}m=\frac{r}{3c}\text{, }&c\neq 0\\m\in \mathrm{C}\text{, }&r=0\text{ and }c=0\end{matrix}\right.$$

Steps for Solving Linear Equation

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

$$3cm=r$$

Divide both sides by 3c.

$$\frac{3cm}{3c}=\frac{r}{3c}$$

Dividing by 3c undoes the multiplication by 3c.

$$m=\frac{r}{3c}$$

Solve for c

$$\left\{\begin{matrix}c=\frac{r}{3m}\text{, }&m\neq 0\\c\in \mathrm{R}\text{, }&r=0\text{ and }m=0\end{matrix}\right.$$
