Jessica is 4 years older than Jeff.
Keisha is twice as old as Jeff.
The total of all three of their ages
is 60. How old is each person?

Respuesta :

Step-by-step explanation:

let age of jeff be x, age of keisha be 2x(since keisha is twice as old as jeff) and age of jessica be x+4 (since jessica is 4 years older than jeff)

Now,

x+2x+x+4=60( since sum of all their ages is 60)

or 4x=60-4

or 4x=56

or x=56/4

or x=14

therefore age of jeff=14

age of keisha=2x=2×14=28

age of jessica=x+4=14+4=18
