Step-by-step explanation:
we have
------> equation A
------> equation B
we know that
If a ordered pair is a solution of the system of linear equations
then
the ordered pair must satisfy equation A and equation B
we're going to verify all the cases
case A)
Substitute the value of x and the value of y in equation A and equation B
Verify equation A
------> is true
the ordered pair satisfy equation A
Verify equation B
the ordered pair satisfy equation B
therefore
the ordered pair is a solution to the system of linear equations
case B)
Substitute the value of x and the value of y in equation A and equation B
Verify equation A
------> is not true
the ordered pair does not satisfy equation A
therefore
the ordered pair is not a solution to the system of linear equations
case C)
Substitute the value of x and the value of y in equation A and equation B
Verify equation A
------> is not true
the ordered pair does not satisfy equation A
therefore
the ordered pair is not a solution to the system of linear equations
case D)
Substitute the value of x and the value of y in equation A and equation B
Verify equation A
------> is not true
the ordered pair does not satisfy equation A
therefore
the ordered pair is not a solution to the system of linear equations
