Answer:

y = -6/7

x = 6/49

Step-by-step explanation:

-7x -y = 0

7x +8y = -6

Add the two equations together to eliminate x

-7x -y = 0

7x +8y = -6

-----------------------

   7y = -6

Divide by 7

7y/7 = -6/7

y = -6/7

Now we need to find x

-7x -y = 0

-7x -(-6/7) =0

-7x +(6/7) =0

-7x +6/7 -6/7 =0-6/7

-7x = -6/7

Divide each side by -7

-7x/-7 = -6/7 *-1/7

x = 6/49

C) They satisfy equation A but not equation B


________________
EXPLANATION

4y - 3x = 16

4(0.25) - 3(-5) = 16

1 -3(-5) = 16

1 + 15 = 16

16 = 16



-x - 8y = 3

-5 - 8(0.25) = 3

-5 - 2 = 3

-7 = 3

Doesnt solve equation B

(Please mark me brainliest it would be much appreciated)
