Solve r=12dm

$$r = 12 dm$$

Solve for d (complex solution)

$$\left\{\begin{matrix}d=\frac{r}{12m}\text{, }&m\neq 0\\d\in \mathrm{C}\text{, }&r=0\text{ and }m=0\end{matrix}\right.$$

Steps for Solving Linear Equation

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

$$12dm=r$$

The equation is in standard form.

$$12md=r$$

Divide both sides by 12m.

$$\frac{12md}{12m}=\frac{r}{12m}$$

Dividing by 12m undoes the multiplication by 12m.

$$d=\frac{r}{12m}$$

Solve for m (complex solution)

$$\left\{\begin{matrix}m=\frac{r}{12d}\text{, }&d\neq 0\\m\in \mathrm{C}\text{, }&r=0\text{ and }d=0\end{matrix}\right.$$

Steps for Solving Linear Equation

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

$$12dm=r$$

Divide both sides by 12d.

$$\frac{12dm}{12d}=\frac{r}{12d}$$

Dividing by 12d undoes the multiplication by 12d.

$$m=\frac{r}{12d}$$

Solve for d

$$\left\{\begin{matrix}d=\frac{r}{12m}\text{, }&m\neq 0\\d\in \mathrm{R}\text{, }&r=0\text{ and }m=0\end{matrix}\right.$$
