The sum of twice a number x and three times a number y is 69. The different between four times number x and twice number y is 18. What are the numbers x and y?

• 2x + 3y = 69 and 4x - 2y = 18

  x = 15 and y = 12

• 3x + 2y = 69 and 4x - 2y = 18

  x = 16 and y = 12

• 2x + 3y = 69 and 4x - 2y = 18

  x = 12 and y = 15

• 3x - 2y = 69 and 4x + 2y = 18

  x = -16 and y = 12
