$P = 2l + 2w$

$P - 2l = 2w$

$\frac{P-2l}{2} = w$

are you trying to solve these first yourself?
they are very basic

3. $P = 2l + 2w$

Subtract $2l$ from both sides.

$P - 2l = 2w$

Divide by $2$ on both sides.

$\frac{P - 2l}{2} = w$

Simplify the right side.

$\frac{P}{2} - l = w$

4. Solve the following equation for w please: P = 2L + 2W.

First, get the w term by its self. To accomplish this, simply subtract 2L from both the right and left hand sides. So, P - 2L = 2W. Finally, divide both sides by 2. $\frac{P-2L}{2} = W$. Flip this equation around to make it look a bit better: $W = \frac{P-2L}{2}$.

There ya have it... W all by its lonesome naked self.
