Solve for L: P = 2L + 2W

A L = P - 2W

B L is equal to P minus 2W all over 2

C L = 2 (P - 2W)

D L = P - 2L - W

B L is equal to P minus 2W all over 2

Step-by-step explanation:

P = 2L + 2W

We want to isolate L.

The first step is to subtract 2W from each side.

P-2W = 2L + 2W-2W

P-2W = 2L

Now divide each side by 2

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

(P-2W) / 2 = L
