Question 765087: For Two Natural Numbers x and y, if 2x-1 <= 4 and 2x+2y <= 7. Find the possible values of y.

You can put this solution on YOUR website! Natural numbers are the counting numbers: 1, 2, 3....
2x-1 <= 4
2x <= 5
x<=5/2 so x is 2 or 1.
2x+2y <= 7(use x=1)
2 + 2y <= 7
2y <= 5
y <= 5/2 so y = 2 or 1.
2x+2y <= 7 (use x=2)
4 + 2y <= 7
2y <= 3
y <= 3/2 so y = 1
Sometimes 0 is considered a natural number. In that case, any of the above could include 0 for y. And if x = 0:
2y <= 7
y <= 7/2 so y could be 3, 2, 1 or 0
