(1) +3x+%2B+1+%3E+-10+
(2) +3x+-+1+%3C+-5+
---------------------------
(1) +3x+%3E+-11+
(1) +x+%3E+-11%2F3+
and
(2) +3x+%3C+-4+
(2) +x+%3C+-4%2F3+
----------------------
Combine (1) and (2)
+-11%2F3+%3C+x+%3C+-4%2F3+
----------------------
Note that the < and > signs are pointing
the right way even though the order of
(1) or (2) might be different.
Hope this helps
