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

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.
