Question

P=2l+2w for w

Answer 1

Bring the desired variable to one side first, and then divide/multiply everything left to isolate the variable.

P = 2l + 2w
2w = P - 2l
w = (P - 2l) / 2

Answer 2

I'm thinking that's 2 and an L, right? Not 21? If so,

2w + 2l = p
2w = p - 2l
w = (p - 2l)/2
w = p/2 - l

Answer 3

P = 2l + 2w
subtract 2l from both sides
P - 2l = 2w
divide by 2
(P- 2l)/2 = w
w = (P - 2l)/2

Answer 4

derive the formula for w:

P=2l + 2w
P-2l=2w
(P-2l)/2=w

(find ways like subtracting to everything other than w to the other side...)

Answer 5

P = 2l + 2w

First, we have to transform de "l" and "P" so it goes :

w = xy + 2 + 2

We now have to extract the square of this total :

w = xy + 16

Now, 16 in numerology equals 1 + 6 = 7 :

w = xy + 7

We must then contain the "y" in another place for the moment (we will come back with it afterwards) :

w = x + 7

7 is the seventh letter of the alphabet (G) so :

w = x + g

Now we have to exchange the "y" for another letter. I'll take the "t" and multiply it with the others.

w = gtx.

So we now have an old car.

Answer 6

Um, don't you need values?

Or do you mean like,
P - 2l = 2w
P - 2l / 2 = w

Answer 7

P=2L+2W
P/2L=2W
P/4L=W

W=P/4L

Edit: You may be asking the question inappropriately.

Answer 8

w=(p-2L)/2

Answer 9

w=(p-21)/2

Answer 10

2 w = p - 2 l
w = (p / 2) - l
