Answer:
B (-9,−57/8)
Step-by-step explanation:
we know that
If a ordered pair is a solution of the linear equation, then the ordered pair must satisfy the linear equation
we have

<u><em>Verify each case</em></u>
Substitute the value of x and the value of y in the linear equation and then compare the results
case A) (6,17/2)
For x=6, y=17/2
Substitute

-----> is not true
therefore
The ordered pair not satisfy the equation
case B) (-9,-57/8)
For x=-9, y=-57/8
Substitute

-----> is true
therefore
The ordered pair satisfy the equation
case C) (6,-39/8)
For x=6, y=-39/8
Substitute

-----> is not true
therefore
The ordered pair not satisfy the equation
case D) (6,-8)
For x=6, y=-8
Substitute

-----> is not true
therefore
The ordered pair not satisfy the equation
Answer:
x=-7, y=2. (-7, 2).
Step-by-step explanation:
x-y=-9
x+y=-5
-----------
2x=-14
x=-14/2
x=-7
-7-y=-9
y=-7-(-9)
y=-7+9
y=2
