Given:
[tex]P=2L+2W[/tex]
Required:
We need to solve for L.
Explanation:
Consider the given equation.
[tex]P=2L+2W[/tex]
Subtract 2W from both sides.
[tex]P-2W=2L+2W-2W[/tex][tex]P-2W=2L[/tex]
Divide both sides by 2.
[tex]\frac{P-2W}{2}=\frac{2L}{2}[/tex][tex]\frac{P-2W}{2}=L[/tex][tex]\frac{P}{2}-\frac{2W}{2}=L[/tex][tex]\frac{P}{2}-W=L[/tex]
Final answer:
[tex]L=\frac{1}{2}P-W[/tex]
