E Correct answer
Explanation

From equation I: x² - 25 = 0, so x² = 25 and x = ±5. From equation II: y² - 4 = 0, so y² = 4 and y = ±2. Since x can be -5 or 5 and y can be -2 or 2, we have multiple possible relationships: x > y (when x=5 and y=2), x > y (when x=-5 and y=-2), x > y (when x=5 and y=-2), but x < y (when x=-5 and y=2). Because the relationship changes depending on which values we choose, it cannot be uniquely determined.
