Problema Solution
Abraham is 5 years older than Belen. The sum of Belen's age and Celeste's age is 15 years less than twice Abraham's age. If the sum of their three ages is 75, how old are Abraham, Belen, and Celeste?
Answer provided by our tutors
let 'a' represent Abraham, 'b' represent Belen and 'c' represent Celeste.
a=b-5
b+c=2a-15
a+b+c=75
