Answer: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 ysubstitute the value of x in any equation

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

therefore

Verify each statementa) 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)
