Which statements are true about the ordered pair (5, −6) and the system of equations? {x+y=−1 3x−y=21 Select each correct answer
Likurg_2 [28]

The correct options are:

The ordered pair (5, −6) is a solution to the first equation because it makes the first equation true.

The ordered pair (5, −6) is not a solution to the system because it makes at least one of the equations false.

Step-by-step explanation:

Given equations are:

x+y=-1\\3x-y=21

first of all we have to put the point in both equations to check if the point holds true on both equations

So,

Putting the point in the first equation

x+y=-1\\5-6=-1\\-1=-1

Putting the point in second equation

3x-y=21\\3(5)-6=21\\15-6=21\\9\neq 21

So,

The correct options are:

The ordered pair (5, −6) is a solution to the first equation because it makes the first equation true.

The ordered pair (5, −6) is not a solution to the system because it makes at least one of the equations false.
