Does the inequality |x + 1| < 0 has a solution?

No, it does not have a solution.

Explanation:

|a| is absolute value of a i.e. if a is positive than |a| is nothing but a. But if a is negative, |a| is the number itself without its negative sign i.e. only positive a. In other words if a is negative, |a|=-a.

Hence |a| is always positive and the lowest value can only be 0. Hence, it is not possible to have absolute value of any number to be negative as absolute value is always greater than or equal to one and hence there is no solution for |x+1|<0.
