Question

Which ordered pair is the solution to the system of equations?

2x+y=-8
x-y=-4
A.
(−3, −2)

B.
(−1, 3)

C.
(1, 5)

D.
(−4, 0)

Answer 1

`2x+y=-8\\ x-y=-4\\ ------\\ 3x=-12\\ x=-4\\\\ -4-y=-4\\ -y=0\\ y=0\\\\ (-4,0) \Rightarrow D`

Answer 2

2x+y=-8
x-y=-4
+------------
3x= -12
x= -4

x-y= -4
-4 -y= -4
y=0

This questin answer is D(-4,0)

Hope this helps :))
