Multiple choice

In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and give answer: (I. 13x - 8y + 81 = 0 ) (II. 15x + 5y + 65 = 0)

  1. x > y

  2. x ≥ y

  3. x < y

  4. x ≤ y

  5. x = y or relation can’t be established

C Correct answer
Explanation

Solving the system: From I: 13x = 8y - 81 → x = (8y-81)/13. Substitute into II: 15(8y-81)/13 + 5y + 65 = 0 → (120y-1215+65y+845)/13 = 0 → 185y - 370 = 0 → y = 2. Then x = (16-81)/13 = -65/13 = -5. Since x=-5 < y=2, option C is correct.
