Can someone explain this to me?

7 × 9 > 50 + ....

The answer is 9. How does that equal 9 and how do you work it out?

63 > 50 + n

63 - 50 > n

13 > n

The answer is infinity :L
@SW-User 13 is not greater than infinity.

@AcidBurn The number of possible answers is infinity :p

Interval notation gives that the set is: (13,-∞)
Which is infinite

If you mean in terms of one solid answer, you can choose between the limits

@SW-User I thought the answer was 13 too. But the quiz said 9.

The answer is a set :/
I don't know how they got 9
