Easy, any *positive* value x will result in -x being negative. So x = 0.0001, x = pi, x = 2, x = 300 million, x = 6 * 10^23, etc. are all valid answers.
Invalid answers would be 0 or anything negative, because the negative of a negative is positive. And the opposite of zero is zero (which is non-negative).

Right now, it's 25 degrees celsius here. If X is the room temp where I am, -x is negative.

The answer is ALL POSITIVE NUMBERS will yield a negative answer for -x.
Sample:
Say, x = 30.
Then -(30) = -30
