What is the question

Answer:

  • Ava is 29

Step-by-step explanation:

It is assumed you are looking for Ava's age.

Let Ava's age be x, then the ages of the other's are:

  • x - 2, x - 4 and x - 6

Sum of the four ages is 104.

Show this as equation and solve for x:

  • x + x - 2 + x - 4 + x - 6 = 104
  • 4x - 12 = 104
  • 4x = 104 + 12
  • 4x = 116
  • x = 116/4
  • x = 29

Ava is 29 years old.
