Which statements are true about the ordered pair (−1, 5) and the system of equations? {x+y=4x−y=−6 Select each correct answer. The ordered pair (−1, 5) is a solution to the first equation because it makes the first equation true. The ordered pair (−1, 5) is a solution to the second equation because it makes the second equation true. The ordered pair (−1, 5) is not a solution to the system because it makes at least one of the equations false. The ordered pair (−1, 5) is a solution to the system because it makes both equations true.
