Solve P=R*L/A

$$P = \frac { R \times L } { A }$$

Solve for L (complex solution)

$$\left\{\begin{matrix}L=\frac{AP}{R}\text{, }&R\neq 0\text{ and }A\neq 0\\L\in \mathrm{C}\text{, }&P=0\text{ and }R=0\text{ and }A\neq 0\end{matrix}\right.$$

Steps for Solving Linear Equation

Multiply both sides of the equation by A.

$$PA=RL$$

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

$$RL=PA$$

The equation is in standard form.

$$RL=AP$$

Divide both sides by R.

$$\frac{RL}{R}=\frac{AP}{R}$$

Dividing by R undoes the multiplication by R.

$$L=\frac{AP}{R}$$

Solve for A

$$\left\{\begin{matrix}A=\frac{LR}{P}\text{, }&L\neq 0\text{ and }R\neq 0\text{ and }P\neq 0\\A\neq 0\text{, }&\left(L=0\text{ or }R=0\right)\text{ and }P=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Variable A cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by A.

$$PA=RL$$

The equation is in standard form.

$$PA=LR$$

Divide both sides by P.

$$\frac{PA}{P}=\frac{LR}{P}$$

Dividing by P undoes the multiplication by P.

$$A=\frac{LR}{P}$$

Variable A cannot be equal to 0.

$$A=\frac{LR}{P}\text{, }A\neq 0$$

Solve for L

$$\left\{\begin{matrix}L=\frac{AP}{R}\text{, }&R\neq 0\text{ and }A\neq 0\\L\in \mathrm{R}\text{, }&P=0\text{ and }R=0\text{ and }A\neq 0\end{matrix}\right.$$
