    Answer:

    • Jonathan: 32
    • Margo: 13

    Step-by-step explanation:

    Let m represent Margo’s age. Then Jonathan’s age is 6+2m, and the sum of their ages is …

      m + (6+2m) = 45

      3m = 39 . . . . . . . . . subtract 6

      m = 13 . . . . . . . . . . . divide by 3

      45 -13 = 32

    Margo’s age is 13; Jonathan’s age is 32.
