The answer to the question is:
The solution to this inequality is the set of ALL REAL NUMBERS.
In other words, any real number x is the solution.
All you need to know to get this answer/(this solution) is the fact that the "absolute value" is ALWAYS positive / (non-negative).
Therefore, the given inequality is TRUE (is satisfied) at any value of x.
