Answer quick 65 points ! !
which statements are true about the ordered pair (7, 19) and the system of equations?
{2x−y=−5x+3y=22
select each correct answer.
the ordered pair (7, 19) is a solution to the first equation because it makes the first equation true.
the ordered pair (7, 19) is a solution to the second equation because it makes the second equation true.
the ordered pair (7, 19) is not a solution to the system because it makes at least one of the equations false.
the ordered pair (7, 19) is a solution to the system because it makes both equations true.
