Answer:
A = - 2 and B = - 8
Step-by-step explanation:
A = - 2 and B = - 8 will create infinitely many solutions for this system of equations
When you add both equations together and both sides are equal then the systems have infinitely many solutions
-2x - y = 8
2x + y = -8
--------------------Add
0 = 0
Both sides are equal 0
Infinitely many solutions
