The formula to find the perimeter of a rectangle is: P = 2W + 2L.

To solve for " W " in this formula, which steps should be followed?

A.) Subtract 2L from both sides of the equation, then subtract 2 from both sides of the equation.
B.) Subtract 2L from both sides of the equation, then divide both sides of the equation by 2.
C.) Divide both sides of the equation by 2L, then subtract 2 from both sides of the equation.
D.) Divide both sides of the equation by 2L + 2

Solving for w means getting w by itself on one side of the equation and everything else on the other. Remeber that to do that, you just need to make sure whatever you do to one side, you do to the other. You want something that looks like W= ______  . What two things would you need to do to accomplish this. Hint: on the right side of your equation, things are being added and multiplied, how would you "undo" those two operations?
