The equation provided is:

$P = 2L + 2W$

You are asked to solve for $W$.

To solve for $W$:

1. Subtract $2L$ from both sides of the equation to start isolating $W$:

$P - 2L = 2W$

2. Next, divide both sides by 2 to solve for $W$:

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

So, the solution for $W$ is:

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