Question

1. solve $p = 2l + 2w$ for $l$

Explanation:

Step1: Subtract \(2w\) from both sides

\(P - 2w = 2l + 2w - 2w\)
Simplifying the right side gives \(P - 2w = 2l\)

Step2: Divide both sides by 2

\(\frac{P - 2w}{2} = \frac{2l}{2}\)
Simplifying gives \(l = \frac{P - 2w}{2}\) or we can also write it as \(l=\frac{P}{2}-w\)

Answer:

\(l=\frac{P - 2w}{2}\) (or \(l=\frac{P}{2}-w\))
