Explanation:
We are solving for the variable y in each equation. Each equation is of the form:
  (number) × y = (result)

To find y, we divide both sides by the number multiplying y. That is:
  y = (result) ÷ (number)

Let’s go one by one:

1. y × 6 = 12 → y = 12 ÷ 6 = 2
2. 9 × y = 18 → y = 18 ÷ 9 = 2
3. y × 5 = 15 → y = 15 ÷ 5 = 3
4. 1 × y = 6 → y = 6 ÷ 1 = 6
5. y × 3 = 12 → y = 12 ÷ 3 = 4
6. 9 × y = 9 → y = 9 ÷ 9 = 1
7. 9 × y = 63 → y = 63 ÷ 9 = 7
8. 2 × y = 2 → y = 2 ÷ 2 = 1
9. y × 9 = 81 → y = 81 ÷ 9 = 9
10. y × 1 = 5 → y = 5 ÷ 1 = 5
11. 7 × y = 49 → y = 49 ÷ 7 = 7
12. 7 × y = 7 → y = 7 ÷ 7 = 1
13. y × 4 = 36 → y = 36 ÷ 4 = 9
14. y × 9 = 27 → y = 27 ÷ 9 = 3
15. 4 × y = 24 → y = 24 ÷ 4 = 6
16. 6 × y = 48 → y = 48 ÷ 6 = 8
17. 8 × y = 40 → y = 40 ÷ 8 = 5
18. 3 × y = 9 → y = 9 ÷ 3 = 3
19. 6 × y = 30 → y = 30 ÷ 6 = 5
20. y × 5 = 25 → y = 25 ÷ 5 = 5
21. y × 5 = 30 → y = 30 ÷ 5 = 6

Double-check a few to be safe:
- #7: 9 × 7 = 63 ✔
- #14: 9 × 3 = 27 ✔
- #16: 6 × 8 = 48 ✔
- #21: 5 × 6 = 30 ✔

All correct.

Final Answer:
2, 2, 3, 6, 4, 1, 7, 1, 9, 5, 7, 1, 9, 3, 6, 8, 5, 3, 5, 5, 6
