Solve W=P/2-2L

$$W = \frac { P } { 2 } - 2 L$$

Solve for L

$$L=\frac{P-2W}{4}$$

Steps for Solving Linear Equation

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

$$\frac{P}{2}-2L=W$$

Subtract \frac{P}{2} from both sides.

$$-2L=W-\frac{P}{2}$$

Multiply both sides of the equation by 2.

$$-4L=2W-P$$

Divide both sides by -4.

$$\frac{-4L}{-4}=\frac{2W-P}{-4}$$

Dividing by -4 undoes the multiplication by -4.

$$L=\frac{2W-P}{-4}$$

Divide 2W-P by -4.

$$L=\frac{P}{4}-\frac{W}{2}$$

Solve for P

$$P=2\left(2L+W\right)$$

Solution Steps

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

$$\frac{P}{2}-2L=W$$

Add 2L to both sides.

$$\frac{P}{2}=W+2L$$

Multiply both sides of the equation by 2.

$$P=2W+4L$$
