    Answer:12

    Step-by-step explanation:

    Let the age of Ava be x, the age of Aiden be y and the age of Charlie be z.

    Average of their age implies : x + y + z / 3 = 8

    multiplying through by 3, we have:

    x + y + z = 24 ... equation 1

    Also, twice the sum of ages of Ava and Charlie implies

    2 (x + z) = 24

    dividing through by 2, we have

    x + z = 12 ... equation 2

    substituting equation 2 into equation 1, we have

    12 + y = 24

    y = 24 - 12

    y = 12

    Since y represents Aiden's age, this means that Aiden is 12

    12 because 2 times the sum of two variables equaling 24 means the two variables are 6 and therefore, through trial and error, you can find that 12+12=24 and 24 divided by 3 is 8.
