3y - 2x = - 6

12y - 8x = - 24

we can try plugging in each value

A

21 - 2x = - 6

84 - 8x = - 24

27 = 2x

x = 13.5

84 - 13.5 * 8 = - 24

84 - 108 = - 24

this works

__________________________

B

15 - 2x = - 6

60 - 8x = - 24

x = 10.5

60 - 84 = - 24

this works

__________________________

C

- 15 - 2x = - 6

- 60 - 8x = - 24

x = - 4.5

- 60 + 36 = - 24

this works

__________________________

D

- 21 - 2x = - 6

- 84 - 8x = - 24

x = - 7.5

- 84 + 8 * 7.5 = -24

- 84 + 60 = - 24

__________________________

I don't know what to tell you, I don't know the x value, all of these y values are possibilities
