\(x\) and \(y\) are consecutive positive integers and:

\(\left{ \begin{eqnarray*} x &>& y\\ x^2 - 1 &>& y^2 - 4y + x - 1\\ \end{eqnarray*}\)

Which of the following represents all the possible values of \(y\) ?

* \(y \ge 0\)

* \(y > 0\)

* \(y > 1\)

* \(y > 7\)

* \(y > 8\)

No creative solution from me I'm sorry, I'm also going for B.

Explanation:

By definition of condition 1, x>y, therefore x=y+1 (since they are consecutive)

I then just plugged in values, starting from y=1, x=2; y=1 seems to work, therefore y>0 is my answer. Note I start from y=1, as y=0 is not possible due to question conditions (y is positive integer)

Seems a bit too straight forward though, what did I miss?
