Answer:
[tex]w=2(P+2b)[/tex]
Step-by-step explanation:
[tex]4P=2w-8b[/tex]
Switch sides:
[tex]2w-8b=4P[/tex]
Add 8b to both sides:
[tex]\2w-8b+8b=4P+8b[/tex]
[tex]2w=4P+8b[/tex]
Divide both sides by 2:
[tex]\frac{2w}{2}=\frac{4P+8b}{2}[/tex]
[tex]w=2P+4b[/tex]
Factor out the common factor (2):
[tex]w=2\left(P+2b)[/tex]
