for it to be a solution, it has to satisfy both inequalities... subbing in (-4,-1) 2x + y < -5                           -x + y > 0 2(-4) - 1 < - 5                      -(-4) - 1 > 0 -8 - 1 < -5                              4 - 1 > 0 -9 < -5.....true                        3 > 0....true solution is (-4,-1)
