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
[tex]\frac{P}{2}-\frac{2L}{2}=W[/tex]
P/2 is the same thing as [tex]\frac{1}{2}P[/tex]
and the 2's in the next term cancel out:
[tex]\frac{2L}{2}=L[/tex]
Putting all that together gives you a solution of
[tex]W=\frac{1}{2}P-L[/tex]
