Original post with discussion is here -> graphic-approach-to-problems-with-inequalities-68037.html
Both the graphic and algebraic approaches have been discussed. I am not very comfortable with the graphic approach. When I first gave the gmat, I received a black ink marker with which I was supposed to work on the checkered sheet(grid is dark in color as well). So I was a little flustered byt his. (Do they provide a marker of different color on request?? I didn't ask them then).
Anyways, my point is that probably I can make sense of the graphic approach on a blank piece of paper but on a checkered one, it can get confusing and it is pretty easy to make mistakes.
Does anyone know of any alternate, non-graphic (& easier) approach to the above problem i.e. apart from those discussed in the post ?
I believe this is pretty much a 700+ (if not 750+) question.
