A Correct answer
Explanation

For equation I: 4x² + 23x + 15 = 0. Factoring: (4x + 3)(x + 5) = 0. So x = -3/4 = -0.75 or x = -5. For equation II: 4y² - 14y + 10 = 0. Divide by 2: 2y² - 7y + 5 = 0. Factoring: (2y-5)(y-1) = 0. So y = 2.5 or y = 1. Both values of x (-0.75, -5) are less than both values of y (1, 2.5). Therefore x < y is correct.
