Given parameters :
- Camille is 7 years older than Donny
- 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
