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.
- 6) is a solution to the first equation because it makes the
the ordered pair (5
first equation true.
the ordered pair (5 - 6) is a solution to the second equation because it makes
the second equation true.
the ordered pair (5 - 6) is not a solution to the system because it makes at least
one of the equations false.
the ordered pair (5,
equations true.
- 6) is a solution to the system because it makes both

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 a solution to the second equation because it makes  the second equation true

The ordered pair (5 - 6) is a solution to the system because it makes both  equations true

Step-by-step explanation:

we have

--- equation A

----> equation B

we know that

If a ordered pair is a solution of the system of equations, then the ordered pair must satisfy both equations

Solve the system of equations by elimination

Adds equation A and equation B

Find the value of y

substitute the value of x in any equation

The solution of the system is the point (5,-6)

therefore

Verify each statement

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

The statement is true (see the procedure)

b) The ordered pair (5 - 6) is a solution to the second equation because it makes  the second equation true

The statement is true (see the procedure)

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

The statement is false (see the procedure)

d) The ordered pair (5 - 6) is a solution to the system because it makes both  equations true

The statement is true (see the procedure)

do you mean add both of the equations together

because if you do the answer is 10x-5
