p=2w+2L

answers:
Owen say: p=2w+2L
Take away p from both sides
2w + 2L - p = 0
Take away 2w from both sides
2L - = 2w
Divide both sides by 2
(2L - p)/2 = w
-
Caroline say: w = (p - 2L)/2
-
Brainard say: p = 2w + 2L
p - 2L = 2w
(p - 2L)/2 = w
w = (p - 2L)/2
-
Jim Moor say: p=2w+2L
subtract 2L from both sides
p-2L = 2w
divide all terms by 2
p/2 -L = w
flip sides
w = p/2 -L
-
Como say: 2w = P - 2L
w = P/2 - L
-
Michael say: Well,
p = 2w+2L
therefore
2w + 2L = p
2w + 2L - 2L = p - 2L
2w + 0 = p - 2L
2w = p - 2L
1/2 * 2 * w = 1/2 * (p - 2L)
1 * w = 1/2 * p - 1/2 * 2 * L
w = p/2 - 1 * L
w = p/2 - L

hope it' ll help !!

alex say: 1st step
2w=p-2L
w=...
-
D.W. say: w = p/2 - L
-
Brain Juice say: p = 2w + 2L -> = 2(w+L) --> 1/2p = w + L --> w = 1/2p - L
