I. x² – x – 42 = 0,
II. y² – 17y + 72 = 0 to solve both the equations to find the values of x and y?

A. If x < y
B. If x > y
C. If x ≤ y
D. If x ≥ y
E. If x = y or the relationship between x and y cannot be established.

Explanation:

I. x² – 7x + 6x – 42 = 0
=> (x – 7)(x + 6) = 0 => x = 7, -6
II. y² – 8y – 9y + 72 = 0
=> (y – 8)(y – 9) = 0 => y = 8, 9
=> x < y

Correct Answer: If x < y ✔
