For statement the combined statements could we consider (based on statement 2) y (positive) to X ( negative odd exponent) = fraction ( which satisfies the statement.

So there would still be the possibility of Y > X when the statements are combined.

Hi Jihan
Y must be negative to satisfy statement (2). If y is positive, then y^x will be positive, no mater what the value of x. So the case you described would not satisfy both statements.

Combining the statements, y MUST be negative, and since x + y > 0, we know that x > 0 and therefore x > y. I hope that helps.
