Answer:

  • Luna is 9
  • Camila is 18
  • Ava is 24

Step-by-step explanation:

We can express all of the ages in terms of Luna's age. Letting L represent Luna's age, we have ...

  • Luna's age: L
  • Camila's age: 2L
  • Ava's age: 2L +6

The total of their ages is then ...

  L +2L +(2L+6) = 51 . . . . an equation with one variable

  5L = 45

  L = 9

Luna is 9, Camila is 18, and Ava is 24.
