Respuesta :

We have that the solutions of the system are

[tex]x\text{ = -6 and y = -1}[/tex]

So we are going to check which of the answers give that answer, we are going to try with A fisrt

[tex]x\text{ = }3(-1)\text{ }-3\text{ = -6}[/tex]

So with A, the solutions are the same, so we have that the answer is A.
