Problema Solution
jake is 5 years younger than twice the age of cal, and lila is 4 years older than jake. the sume of all their ages is 59. how old is lila
Answer provided by our tutors
let
j = the age of Jake
c = the age of Cal
l = the age of Lila
Jake is 5 years younger than twice the age of Cal:
j = 2c - 5
Lila is 4 years older than Jake:
l = 4 + j
the sum of all their ages is 59:
j + c + l = 59
by solving the system of equations:
j = 2c - 5
l = 4 + j
j + c + l = 59
we find:
j = 21
c = 13
l = 25
