Substitute in numbers
-|2|=-2 or -|-2|=-2. We can't use 0 as x or b due to the original condition.

I) The negative sign is outside of the absolute value sign. Thus, the negative is applied to a positive number. B is negative. b<0.
II) 2<--2(x) as they are equal; -2<--2 (o)
III) 2>-2(o); -2>-2(x) as they are equal

b can be any integer other than 0.
Case 1 : If x > 0 , b is < 0
Case 2 : If x < 0 , b is < 0

Statement I is always true.
Statement II can be true in case 2 but not in case 1
Statement III can be true in case 1 but not in case 2

3 conditions

1. b obviously can take any value
2. b=-1, x=-1 results in -|x|=b, -1=-1 and satisfies x<-b
3. b=-1, x=1 results in -|x|=b, -1=-1 and satisfies x>b
