For the equation x + y = 7, Meena lists the solutions where both x and y are whole numbers (0, 1, 2, ...). How many such whole-number solutions are there?

Question

Accepted Answer

8. x can be 0,1,2,...,7 (then y = 7 - x is a whole number). That is 8 ordered pairs.

For the equation $x + y = 7$ , Meena lists the solutions where both $x$ and $y$ are whole numbers (0, 1, 2, ...).
