Solve the formula P = 2l + 2w for w.

Question

anonymous · Answer

are you asking what is w

anonymous · Answer

P = 2L + 2W

Subtract 2L from both sides:

P - 2L = 2L - 2L + 2W

2L - 2L is 0, so this simplifies

P - 2L = 2W

Now divide both sides by 2

(P - 2L)/2 = 2W/2

2/2 equals 1, which you can leave out in multiplication:

(P - 2L)/2 = W

That's your answer.

W = (P - 2L)/2

anonymous · Answer

Yes .. w=?

anonymous · Answer

P = 2W +2L 
step is keep 2L in one side of equation , and move every thing else to the other side.
 
In moving any quantity from one side to other, change the sign. ( equivalent of adding or subtracting equal                                                                                                  quantity from both sides of equation).
 
2L = P - 2W
 
divide both sides by 2:
 
 L = p/2 - w
 
 Step is the same as solving  X in equation of  8 = 2X + 16
 2X = 8 -16 = 8
   X =4 . But, here you solve one variable in terms of other variables.

oh my bad different equation

anonymous · Answer

P=2l+2w when P will pass = it will be -2l+2w=-P
                                                               2w=-P+2l
                                                                 w=-P+2l/2
