Question

MEDAL & FAN ANYBODY ?
Solve the following equation for w: P = 2l + 2w
a. w=p/2-1
b. w=p/2+1
c. w=p-1/2
d. w=p+1/2

Answer 1

is it 21 or 2l ?

Answer 2

2l it looks like

Answer 3

To solve for W, we need to isolate it to one side of the equation -- doesn't matter which side.
.
P = 2W + 2L
Start by subtracting 2L from both sides:

Answer 4

P - 2L = 2W
Finally, divide both sides by 2:
(P-2L)/2 = W
or, you could write:
P/2 - L = W

Answer 5

therefore the answer is A
