Answer: Grandfather = 62

Grandmother = 59

Step-by-step explanation:

1) Organize information.

  • m + 3 = f
  • f + m = 121
  • m + (m + 3) = 121

2) Simplify.

  • 2m + 3 = 121
  •       -3     -3
  • 2m = 118
  • ÷2     ÷2
  • m = 59

3) Insert value of m into m + 3 = f.

  • 59 + 3 = f
  • 59 + 3 = 62

4) Check work.

  • 59 + 62 = 121?
  • Yes
