This equation cannot be solved to get a single number. Instead just use normal algebra skills to get the w by itself by subtracting 2l from both sides and then dividing by 2.

Answer:

The equation for w is :

\(w=\frac{P}{2}-I\)

Step-by-step explanation:

P = 2w + 2l

Step 1 : Taking 2 common:

\(P=2(w+I)\)

Step 2 : Dividing 2 on both sides:

\(\frac{P}{2}=\frac{2(w+I)}{2}\)

\(\frac{P}{2}=w+I\)

Step 3 : Subtracting I on both sides:

\(\frac{P}{2}-I=w+I-I\)

\(w=\frac{P}{2}-I\)

The equation for w is ;

\(w=\frac{P}{2}-I\)
