Problema Solution
Wilma is twice as old as Jamal, and Jamal is 3 years older than Tim. The sum of all their ages is 17. How old is Jamal?
Answer provided by our tutors
let
x = the age of Jamal
Jamal is 3 years older than Tim:
x - 3 = the age of Tim
Wilma is twice as old as Jamal:
2x = the age of Wilma
The sum of all their ages is 17:
x + (x - 3) + 2x = 17
by solving the above equation we find:
x = 5 years
