Answer: C. (-2, 0)

Step-by-step explanation:

  1. 5x+6y=-10                                                                                                                                 3x-2y=-6
  2. Now you need to get -2 to equal -6 so it cancels out
  3. 5x+6y=-10                                                                                                                                 3(3x-2y)=3(-6)
  4. Then distribute the 3
  5. 5x+6y=-10                                                                                                                                 9x-6y=-18
  6. Now add the equations together
  7. 14x=-28  
  8. Now solve for x: Divide both sides by 14
  9. x=-2
  10. Plug x into either equation to solve for y.
  11. 3(-2)-2y=-6
  12. Distribute -2
  13. -6-2y=-6
  14. Add 6 to both sides
  15. 6 cancels out leaving: -2y=0
  16. Divide both sides by -2
  17. y=0

So, the answer is (-2, 0)! Hope this helps
