Answer:
Not the solution tp the system because the ordered pair should be true for both equations. However the last equation is not true.
Explanation:
(-1,-2) is the solution of the system. x + y =-3 and 2x - y = -4*
x + y =-3 :
(-1)+ (-2) = -3
-1-2 =-2 -3=-3
2x - y = -4:
2(-1)-(-2)=-4
(-2) -(-2)= -4
0=-4
