Question

I don’t understand this problem answer

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

Answer 1

Answer:

b.

Step-by-step 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

$\frac{P}{2}-\frac{2L}{2}=W$

P/2 is the same thing as $\frac{1}{2}P$

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

$\frac{2L}{2}=L$

Putting all that together gives you a solution of

$W=\frac{1}{2}P-L$

Answer 2

The right answer is B. Good luck
