Question

Rewrite without using inequality sign: -7<x<1.​

Answer 1

Answer:

inequality absolute-value

we did this problem in class yesterday and I couldn't replicate our result at home.

|1+x1−x| ≤ 1

How do I algebraically solve this and then display the solution in set notation? I tried rewriting the absolute value as

-1 ≤ 1+x1−x ≤ 1 but then I got stuck. I can't seem to manipulate it to the point where it's obvious for what x this inequality holds true.

Any help appreciated
