Is this an official one ??

2x>x+10 => x>10
x+10>-x => x>-5

The overlap of the 2 conditions is x>10

Solving one at a time, you arrive at x > 10 and x > -5.

It means that x > 10 because if x>10, x is automatically greater than -5.
(The other way is not correct)

Thanks All, that makes sense. I guess I did not know to split the inqualities in the manner that you both did.

This problem was from a Kaplan Workbook assignment. It just gave answer without any explanation and did not have any similar to this.
