Answer:
l = -w + (p/2)
Step-by-step explanation:
Isolate the variable l. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 2w from both sides.
p = 2l + 2w
p (-2w) = 2l + 2w (-2w)
p - 2w = 2l
Isolate the l. Divide 2 from both sides.
(2l)/2 = (-2w + p)/2
l = -w + (p/2)
l = -w + (p/2) is your answer.
