Answer:

  • x = 5/2
  • y = -1.5

Explanation:

  • 5x + y = 11

3x − y = 9

  • => 5x + y = 11

+3x − y = +9

  • => 8x = 20

  • => x = 20/8

  • => x = 5/2

  • => 5(5/2) + y = 11

  • => 25/2 + y = 11

  • => 12.5 + y = 11

  • => y = 11 - 12.5

  • => y = -1.5

Therefore, the answers are:

  • x = 5/2
  • y = -1.5

Hoped this helped.
