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 :

[tex]w=\frac{P}{2}-I[/tex]

Step-by-step explanation:

P = 2w + 2l

Step 1 : Taking 2 common:

[tex]P=2(w+I)[/tex]

Step 2 : Dividing 2 on both sides:

[tex]\frac{P}{2}=\frac{2(w+I)}{2}[/tex]

[tex]\frac{P}{2}=w+I[/tex]

Step 3 : Subtracting I on both sides:

[tex]\frac{P}{2}-I=w+I-I[/tex]

[tex]w=\frac{P}{2}-I[/tex]

The equation for w is ;

[tex]w=\frac{P}{2}-I[/tex]
