**Directions (6-10): In each of the following questions two equations are given solve these equations and give answer. **

**Q6. I. 3x + 5y = 28 **

** II. 8x – 3y = 42**

**Q7. I. 6x² + 23x + 20 = 0 **

** II. 6y² +31y + 35 = 0**

**Q8. I. 4x² - 25x + 39 = 0 **

** II. 18y² - 15y + 3 = 0**

**Q9. I. x² - 72 = x **

** II. y² = 64**

x² - 9x + 8x – 72 = 0

x (x – 9) +8 (x – 9) = 0

x = 9 or -8

II.y² = 64

y = ± 8

No relation

**Q10. I. 30x² + 11x + 1 = 0 **

** II. 42y² + 13y + 1 = 0**
