Rearrange the equation algebraically to solve for the unknown quantity.

3. Solve the equation p = 21 + 2w for l.

1. 2L = P-2W

2. L = P/2-2W

3. L = (P-2W) / 2

4. L = (P + 2W)/2

PLEASE HELP ME !!

Respuesta :

Given:

Consider the given equation is

[tex]P=2L+2W[/tex]

To find:

The solution of the equation for l.

Solution:

We have,

[tex]P=2L+2W[/tex]

Substract 2W from both sides.

[tex]P-2W=2L+2W-2W[/tex]

[tex]P-2W=2L[/tex]

Divide both sides by 2.

[tex]\dfrac{P-2W}{2}=\dfrac{2L}{2}[/tex]

[tex]\dfrac{P-2W}{2}=L[/tex]

[tex]L=\dfrac{P-2W}{2}[/tex]

Therefore, the correct option is 3.
