Discussion

Explanation:

The LHS is of the form: (x – 7) / (x + 9) (x – 4)

For x > 7, the expression will be positive.

Similarly, for any negative integer,

[(x – 7)/(x – 4)] will always be positive.

For the expression to be positive,

(x + 9) > 0 i.e. x > −9

Hence, the smallest integer that satisfies this inequality is x = −8

Hence, option (d)
