Question 1093770
Either x+1 is non-negative or x+1 is negative.


Either {{{x+1>=4}}} Or {{{-x-1>=4}}};

Either {{{x>=3}}} or {{{x<=-5}}}.


--------------------------------------------------------------------------

The solution set might be the combination of both (-infinity,-5] AND [3,infinity), but these two intervals have no points in common.



(Note that you showed an incorrect value for one of your intervals' boundary values.  )


NOT  (-infin,-5]U[5,infin), <b>BUT YOU WANT (-infin,-5]U[3,infin)</b>.
