Hello to everyone. This is my first time here so I hope I will not cause any unwanted trouble. Straight to the problem. I have one inequality for which I would like to prove, but I do not know how. The inequality has the following form:- (1+a)q < q/(1-a), where a < 1 and q can be any positive real number. Can someone hint me the direction to prove this? So far, I tried to tackle the inequality by substituting a with different real number smaller than 1, and there is no discrepancy to the inequality.
