Answer:

  • (5, - 6)

Step-by-step explanation:

Given system:

  • 6x + 3y = 12
  • -2x - 5y = 20

Triple the second equation and add up with the first one to eliminate the variable x:

  • 6x + 3y - 6x - 15y = 12 + 60
  • -12y = 72
  • y = - 6

Find x:

  • 6x - 6*3 = 12
  • 6x - 18 = 12
  • 6x = 30
  • x = 5
