The system is actually not too complicated. If you multiply them out you should get -i < 20 i < 20 -j < 10 i-j < 0 -2i + j < 20 From the 2nd inequality, we have our desired upper bound for i. For the lower bound of -15, combine j > -10 and -2i + j < 20. The 3rd inequality gives us our desired lower bound for j. As for the upper bound of 60, combine i < 20 and -2i+j < 20.
