  1. If x > y

  2. If x ≥ y

  3. If x < y

  4. If x ≤ y

  5. If x = y or relationship can not be established

C Correct answer
Explanation

From equation (II): 7 + 2x = 0, so 2x = -7 and x = -3.5. Substituting x = -3.5 into equation (I): 3(-3.5) + 5y = -20, so -10.5 + 5y = -20, giving 5y = -9.5 and y = -1.9. Since -3.5 < -1.9, we have x < y.
