it is obvious that |[|x|-5]| – 11 should be greater than zero
or |[|x|-5]| should be greater than 11
or [|x|-5] should lie in (-inf,-11)U(11,inf)
or |x|-5 should lie in (-inf, -11)U[12, inf).
or |x| should lie in (-inf, -6)U[17, inf).
but |x| cant lie in (-inf, -6)
so it has to lie in [17, inf).
or x belongs to (-infinity,-17] U [17,infinity)
