    P = 2l + 2w

    P - 2l = 2w

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

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

    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

    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.
    Please learn to master these.
