Is x > 2y?
✓ Correct Answer: Option C
From (1) and (2) together, we solve the system of equations: 3x - 5y = 10 and x + 2y = 15. This yields x = 95/11 and y = 35/11. Substituting these values, 95/11 > 2(35/11) is 95/11 > 70/11, which is true. Neither statement alone is sufficient as both allow for cases where the inequality holds and does not hold.
