During simplification, we should observe that the inequality sign changes due to negative sign. Hence, our final inequality equation read t > - 5 ; thus, arrow should point to the right
if it is solution point (4, –2) must satisfy both equations (1) –3x – 2y = –8-->-3*4-2*(-2)=-8 -12+4=-8 then-->-8=-8 ok (2) y = 2x – 5 -2=2*4-5=3---------->-2 is not 3
the point (4, –2) is not solution of the system of equations
