Question

Which statements are true about the ordered pair (−4, 0) and the system of equations?

{2x+y=−8
x−y=−4
Select each correct answer.
The ordered pair (−4, 0) is a solution to the first equation because it makes the first equation true.
The ordered pair (−4, 0) is a solution to the second equation because it makes the second equation true.
The ordered pair (−4, 0) is not a solution to the system because it makes at least one of the equations false.
The ordered pair (−4, 0) is a solution to the system because it makes both equations true.

Answer 1

2x + y = -8 (-4, 0)
2(-4) + 0 = -8
-8 + 0 = -8
-8 = -8

x - y = -4 (-4, 0)
-4 - 0 = -4
-4 = -4

the ordered pair (-4, 0) is a solution to the system because it makes both equations true.
