Hi, I used a different approach as I figured using cases would take a long time, please let me know if I am wrong:
I opened the modulus sign directly for the case of x being positive
-5 < x+1 + x-2< 5
-4 < 2x < 6
-2 < x < 3
ended up being the correct answer, but I'm sure this isn't a comprehensive method to do the solution. Can this work in most cases?
This is wrong. Check correct solution above.
