Question 252244: If x and y are natural numbers, then how many solutions does the equation
x + y = 12 have?
Answer by Theo(13342)   (Show Source):
You can put this solution on YOUR website! it depends on whether you include 0 as part of the natural number set.
natural number can be either positive integers or non-negative integers.
your equation is x + y = 12.
assuming non-negative integers, then the possible solutions are:
0 + 12
1 + 11
2 + 10
3 + 9
4 + 8
5 + 7
6 + 6
assuming positive integers only, then the possible solutions are the same except that you would remove the 0 as one of the possible solutions.
positive integers DISABLED_event_only= 6 possible ways to add x + y = 12
non-negative integers DISABLED_event_only= 7 possible ways to add x + y = 12
