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. 9  – 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.  – 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
