Question 1096771
<pre>
{{{x<=-5}}}          {{{ -5<=x<=2}}}       {{{2<=x<=6}}}            {{{6<=x}}}
(-)(-)(-)       (+)(-)(-)         (+)(+)(-)         (+)(+)(+)
neg              pos               neg               pos
TRUE            FALSE             TRUE               FALSE
</pre>


The solution SET is  {{{-infinity<x<=-5}}} AND {{{2<=x<=6}}}.
