  2. If x≤y

  3. If x=y or relationship cannot be established

  4. If x>y

  5. If x≥y

D Correct answer
Explanation

Solving the system: From I, 7x = 29 + 4y, so x = (29 + 4y)/7. Substituting in II: 5(29 + 4y)/7 + 3y = 50. This gives 145 + 20y + 21y = 350, so 41y = 205 and y = 5. Then x = (29 + 20)/7 = 7. Since x = 7 and y = 5, we have x > y.
