A town's oldest inhabitant is x years older than the sum of the ages of the Lee triplets. If the oldest inhabitants is now J years old, how old will one of the triplets F be in 20 years? J-X-40/3 is my answers. J = X + L + L + L is the initial situation After 20 years J + 20 = X + L + L + L + 60 ...20 years for each triplet so 60 years totally. J - X - 40/ 3 = L is my answer. What wrong am i doing ? Since the age asked is after 20 years i also consider adding 20 years to J .
