<pre>
1.  First, it is not an equation.
    It is inequality, instead.


2.  The solution to this inequality is the set of those real "x" in the number line, that are remoted 4 units from the point (-1).

        This set is  (-infinity,-5] U [3,infinity).


    Notice that the points -5  and  3  are included to the solution set.
