Given parameters :

  • Donny is 4 years younger than Tommy

To find :

  • Total ages of the three people

Solution with details :

Let us take the age of Donny as x years - i

According to the given question we have ,

  • Camille's age = x + 7 years
  • Tommy's age - 4 = Donny's age
  • Tommy's age = Donny's age + 4
  • Tommy's age = x + 4 ( from i )

Total ages of three people = Sum of their ages

  • Camille's age + Donny's age + Tommy's age
  • x + 7 + x + x + 4
  • 3x + 11
