Question

Solve each equation or formula for the variable indicated.

$P=2l+2w$ for $l$

Step-by-Step Solution

Answer

The solution of the equation for $l$ is $\frac{P-2w}{2}$.

Step 1. Given information.

We have an equation $P=2l+2w$.

To find the solution of the given equation for $l$.

Step 2. Calculation.

Solving the above equation:

$\begin{array}{l}P=2l+2w\\ \Rightarrow 2l=P-2w\\ \Rightarrow l=\frac{P-2w}{2}\end{array}$

Step 3. Conclusion.

From Above calculation 

$l=\frac{P-2w}{2}$

Hence, the solution of the equation for $l$ is $\frac{P-2w}{2}$.
