I feel this part warrants additional explanation. For me, at least!erjamit wrote:x = ny/(x-1)...now it not necessary that x is a multiple of y. Insufficient.
Well, I look at the statment y is a divisor of x(x-1), and while there could be many possibilities here, one possibility is certainly that y = x-1. And if x > 2, x is not divisible by x-1; the remainder would always be 1 in that case. Choose any x > 2, let y = x-1, and you'll see why the information is insufficient.beeparoo wrote:I feel this part warrants additional explanation.

I got to this point as well, but then considered that
n/(x - 1) can be considered a constant for 'y'.
In this case, I considered x to be a multiple of y. Ack! What is wrong with my conclusion?
