Answer:

Not the solution tp the system because the ordered pair should be true for both equations. However the last equation is not true.

Step-by-step explanation:

(-1,-2) is the solution of the system. x + y =-3 and 2x - y = -4*

<em />

<em>x + y =-3 :</em>

(-1)+ (-2) = -3

-1-2 =-2   -3=-3

<em />

<em>2x - y = -4:</em>

2(-1)-(-2)=-4

(-2) -(-2)= -4

0=-4

0 = -5(4) +4

0 = -20+4
