Question: Check if an expression is greater than another, based on variables


I have 2 expressions, the first expression cosist of x´s and y´s, the other expression consits only of x´s

I wanna test the relation between those 2 expression to check wether A>B giving the condition that 2y<x

I have tried this:



the problem is that maple returns FAIL, I could put in values to check and it works, but that is not really what im trying to acomplish.
