Hi Guys, i'm having a mental block on this very easy inequality problem.

Can some one break this one down for me.

2X > x + 10 > -X

Break it into 2 inequalities:

1: 2x > x+10 --->> x > 10

2: -x < x+10 --->> -2x < 10 --->> x > -5

Take the intersection: x > 10

I don't know if there is a better way to solve it

In 2X > x + 10 > -X

is X and x the same or different variables?
