Question

P=2(l + w) solve for w

Answer 1

Solution:

Consider the following expression:

$p\text{ = 2(l+w)}$

applying the distributive property, we get:

Equation 1:

$p\text{ = 2l +2w}$

solving for 2w, we get:

$2w\text{ = p-2l}$

solving for w, we get:

$w\text{ = }\frac{p-2l}{2}$

now, solving for 2l from equation 1, we get:

$2l\text{ = p-2w}$

solving for l, we get:

$l\text{ = }\frac{p-2w}{2}$

we can conclude that the correct answer is:

$w\text{ = }\frac{p-2l}{2}$

and

$l\text{ = }\frac{p-2w}{2}$
