I already told you. There is no solution to this problem. There is no real number that you can substitute for to make this a true statement.

By definition, the absolute value must be greater than or equal to zero. But in order for -5 to be multiplied by something and achieve a positive result, that something must also be less than zero. But cannot simultaneously be greater than or equal to zero (by definition of absolute value) and less than zero (the product of two negatives is positive).

The solution set is the empty set.
