Answer :

Weare asked to solve for "l" in the expression:

p = 2 l + 2 w

first subtract the term "2 w" from both sides:

p - 2 w = 2 l

Now divide both terms by "2" in order to eliminate the factor 2 that accompanies the unknown "l":

(p - 2 w) / 2 = l

So : l = (p - 2 w)/2

we can also write it as:

l = p/2 - w

if we distribute the division by "2" among the two terms inside the parenthesis.

Please select the appropriate one from any list of options you may have been given.
