My problem is : P=2L+2W solve for L

L = P/2 - W

Explanation:

Step 1 - Start by factoring out the two

P = 2L + 2W

P = 2 (L + W)

Step 2 - Divide both sides of the equation by two

P = 2 (L + W)

P / 2 = 2 (L + W) / 2

P / 2 = L + W

Step 3 - Subtract W from both sides of the equation

P / 2 = L + W

P / 2 - W = L + W - W

P / 2 - W = L

L=P/2-W

Step-by-step explanation:

P=2L+2W

P=2 (L+W)

P/2=L+W

L=P/2-W
