Answer:

x= 4, y=3

Step-by-step explanation:

2x + 3y = 17

3x - 2y = 6

----------

If we double the first and triple the second equation, and add up, we can get rid of y:

  • 4x+6y= 34
  • +
  • 9x - 6y= 18
  • -----------------
  • 13x= 52
  • x= 4

Then it is easy to find the value of y:

  • 2*4+3y= 17
  • 3y= 9
  • y= 3

Answer is: x= 4, y=3
