Hi Kendahl,
This does not equal zero!
-3 < 2x + 1 < 5
-3 -1 < 2x +1 -1 < 5 -1 (subtract -1 from each part of the inequality)
-4 < 2x < 4 (divide everything by 2)
-2 < x < 2
x is in the interval (-2,2)

Agreed, 0 is AN answer but not the complete answer. Was the test multiple choice?

Perhaps if you post the exact wording? The inequality as written defines all possible values for x. There is no other information

Thanks Alan. Yes you are correct. 0 is an answer but no the complete answer. Kendahl, like Mark asked is there more information?

That's exactly what I got too, however the practice test is telling me that it is 0. I assume it is saying that "x=0" because -2<0 but 0<206/24/19
