Question

I don’t understand this problem answer

I thought it is w = P-2L/2

Answer 1

The right answer is B. Good luck

Answer 2

b.

Explanation:

The answer is b. Here are the steps:

Subtract 2L from both sides to get

P - 2L = 2W

Now divide both sides by 2 to get

`(P)/(2)-(2L)/(2)=W`

P/2 is the same thing as
`(1)/(2)P`

and the 2's in the next term cancel out:

`(2L)/(2)=L`

Putting all that together gives you a solution of

`W=(1)/(2)P-L`
