Antonio Garcia · Answer 1

1. P=2l+2w

2. P=2l-2l+2w

3. P-2l=2w

4. P-2l=2w/2

5. (P-2l) = w

Zackery Palmer · Answer 2

P = 2 (L + W) Distribute the 2 into the parenthesis

P = 2L + 2W Subtract 2L from both sides to isolate the 2W

P - 2L = 2W Divide both sides by 2 to isolate the W

(P-2L) / 2 = W
