Answer:

  • x = -1
  • y = 5

Solution:

  • => 6x + 5y = 19

            -3x - 4y = -17

  • => 6x + 5y = 19

           2(-3x - 4y = -17)

  • => 6x + 5y = 19

           -6x - 8y = -34

  • => -3y = -15
  • => 3y = 15
  • => y = 5

Now, let's take one equation and substitute the value of y in it.

  • 6x + 5y = 19
  • => 6x + 5(5) = 19
  • => 6x + 25 = 19
  • => 6x = 19 - 25
  • => 6x = -6
  • => x = -1

Check:

  • => -3x - 4y = -17
  • => -3(-1) - 4(5) = -17
  • => 3 - 20 = -17
  • => -17 = -17

Hence, this is proven correct.

Hoped this helped.
