Question

Solve for w

P = 2L + 2w

Answer 1

Isolate the equation where w is by itself. Subtract -2L on both sides and divide by 2.

Answer 2

P = 2L + 2W

2L + P = 2W

(2L + P)/2 = W

Answer 3

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
