    Ayanna is 17 and Brittany is 14.

    To find this, let's write two equations using the given information.

    a = b + 3

    3b + 2a = 76

    Now, just substitute the first equation into the second and solve.

    3b + 2 (b + 3) = 76

    3b + 2b + 6 = 76

    5b = 70

    b = 14

    If Brittany is 14, then Ayanna is 3 years older at 17.
