Solve W=P/4L

$$W = \frac { P } { 4 L }$$

Solve for L

$$\left\{\begin{matrix}L=\frac{P}{4W}\text{, }&P\neq 0\text{ and }W\neq 0\\L\neq 0\text{, }&W=0\text{ and }P=0\end{matrix}\right.$$

Steps for Solving Linear Equation

Variable L cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by 4L.

$$W\times 4L=P$$

Reorder the terms.

$$4LW=P$$

The equation is in standard form.

$$4WL=P$$

Divide both sides by 4W.

$$\frac{4WL}{4W}=\frac{P}{4W}$$

Dividing by 4W undoes the multiplication by 4W.

$$L=\frac{P}{4W}$$

Variable L cannot be equal to 0.

$$L=\frac{P}{4W}\text{, }L\neq 0$$

Solve for P

$$P=4LW$$

$$L\neq 0$$

Solution Steps

Multiply both sides of the equation by 4L.

$$W\times 4L=P$$

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

$$P=W\times 4L$$
