Quadratic Equation for IDBI Executive 2018: 16 April

Directions (Q. 1 – 10): In each of these questions, two equations (I) and (II) are given. You have to solve both the equations and give answer
1) if x > y
2) if x ≥ y
3) if x < y
4) if x ≤ y
5) if x = y or relationship between x and y cannot be established

1. I. 4 x + 7 y = 42
   II. 3 x – 11 y = –1

2. I. – 29 x + 22 = 0
    II. – 7 y + 12 = 0

3. I. 3 – 4 x – 32 = 0
   II. 2 – 17 y + 36 = 0

4. I. 3 – 19 x – 14 = 0
   II. 2 + 5 y + 3 = 0

5. I. + 14 x + 49 = 0
   II. + 9 y = 0

6. I. 7 – 9 x + 2 = 0
   II. – 4 y + 3 = 0

7. I. x² = 64
   II. 2 + 25 y + 72 = 0

8. I. x² + x – 20 = 0
   II. 2 – 19 y + 45 = 0

9. I. 7 x + 3 y = 26
   II. 2 x + 17 y = – 41

10. I.3 – 20 x + 33 = 0
    II. 2 – 11 y + 15 = 0
