Multiple choice

In each of the following questions, two equations (I) and (II) are given. You have to solve them and give answer. $(I) (5x + 7y = 35) (II) (10x + 14y = 42)$

  1. If x > y

  2. If x ≥ y

  3. If x < y

  4. If x ≤ y

  5. If x = y or relationship can not be established

E Correct answer
Explanation

Equation I: 5x + 7y = 35. If we multiply by 2, we get 10x + 14y = 70. Equation II: 10x + 14y = 42. This is impossible - the same expression cannot equal both 70 and 42. The system is inconsistent with no solution, so relationship between x and y cannot be established.
