1. I. 6x² – 19x + 15 = 0
II. 10y² – 29y + 21 = 0
A. if x > y
B. if x < y
C. if x ≥ y
D. if x ≤ y
E. if x = y or no relation can be established between ‘x’ and ‘y’.
2. I. 12x² + 11x – 56 = 0
II. 4y² – 15y + 14 = 0
A. if x > y
B. if x < y
C. if x ≥ y
D. if x ≤ y
E. if x = y or no relation can be established between ‘x’ and ‘y’.
3. I. 3x² + 13x + 12 = 0
II. y² + 9y + 20 = 0
A. if x > y
B. if x < y
C. if x ≥ y
D. if x ≤ y
E. if x = y or no relation can be established between ‘x’ and ‘y’.
4. I. 8x² – 15x + 7 = 0
II. 2y² – 7y + 6 = 0
A. if x > y
B. if x < y
C. if x ≥ y
D. if x ≤ y
E. if x = y or no relation can be established between ‘x’ and ‘y’.
5. I. 7x – 3y = 13
II. 5x + 4y = 40
A. if x > y
B. if x < y
C. if x ≥ y
D. if x ≤ y
E. if x = y or no relation can be established between ‘x’ and ‘y’.
