t can't be 1 or 2 by the 2nd and 3rd inequality. Also, k > 4-t which tell us t can't be 4 so t is 1, 2, or 3 but we know t isn't 1 or 2.
Both t and k are positive integers. What is the value of t? Multiple choice: 1, 2, 3, 4, or 5
I'm confused by the way this is worded... It seems to say that there is only one value of t which satisfies this system. But if I graph this, I get an entire region, not just one value? In fact, it would seem if I graph this I get no overlap of shaded regions. I don't get it.
I guess one way is to just start trying numbers, but there must be a better way?
