Solve the following system of equations.
8x + 4y = -40
3x + y = -8
OA. x = 2, y = -14
OB. x = -14, y = 2
O
C. x = 12, y = -44
OD. x = 5, y = -20
Please help

Answer:

8x + 4y = - 40

We can divide both sides by 4

2x + y = - 10

3x + y = - 8

If wa substract first one from the other one we have :

2 = x

So y = - 10 - 4 = - 14

OA is correct
