Answer:
Option D.
Step-by-step explanation:
we have
-----> equation A
-----> equation B
Solve the system by elimination
Multiply both sides equation A by -1

-----> equation C
Adds equation C and equation B

<em>Find the value of x</em>
substitute the value of y in either equation

The solution is the point (-1,2)
In this problem Option A,B and C are correct
The option D not result in a system with a pair of opposite terms
because
Multiply both sides of equation B by -3

-----> equation C
Multiply both sides of equation A by 5
----> equation D
so
equation C and equation D not have a pair of opposite terms
