My second grader brought home this math problem for which I can find no solution. The sum of two numbers is 21. One number is two more than the other. What are the two numbers?

  • Math -

    x+y = 21
    x = y + 2
    2y + 2 = 21
    y = 19/2
    x = 23/2

    This is for a second grader. He only works in WHOLE numbers still. I believe this was a mistake on the teachers' part. Should have been "one number is 3 more than the other", I think.
    Thank you for your help.

  • Math -

    y = 9
    x = 12
