Question

Is (6, -6) a solution to the system
- 4x – 2y = -12
4x + 8y = -24
Yes
No

Answer 1

`- 4x - 2y = - 12 \\ 4x + 8y = - 24 \\ \\ 6y = - 36 \\ y = ( - 36)/(6) = - 6 \\ \\ - 4x - 2( - 6) = - 12 \\ - 4x + 12 = - 12 \\ - 4x = - 12 - 12 \\ - 4x = - 24 \\ x = ( - 24)/( - 4) = 6`

yes it's a right answer

Answer 2

Yes (6, -6) is a solution to the system.
