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 +

Since the 2L is not being multiplied or divided, and it's positive, we will subtract it from both sides. Since the W is being multiplied by the 2, we'll also need to divide both sides by 2. 

Your answer is B.
