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.
