If I try this question in different ways I get a different answer:
For positive ,
Find the numerical value of

Nope, it works for all k, supposedly.

-Dan actually, it is true otherwise. did you try other values for k?
Ooops, look how I canceled the x's in the first solution. Happens way to much.
if (2y +x)/x = x/y
Then (2y +x) is not equal to y.

The first one says:
and the second says
Now define and and you get the system:
You are after the value of a.
Interesting approach @ topsquark
geeze, you guys are replying so faast today
