Answer: [tex]W=\frac{P-2L}{2}[/tex]
Step-by-step explanation:
[tex]P=2L+2W[/tex]
Isolate 2W by substracting 2L on both sides.
[tex]-2L+P=2L+2W-2L[/tex]
[tex]-2L+P=2W[/tex]
Isolate W by dividing by 2.
[tex]\frac{-2L+P}{2} =\frac{2W}{2}[/tex]
[tex]\frac{-2L+P}{2}=W[/tex] or [tex]W=\frac{P-2L}{2}[/tex]
It's the same.
