答案解析部分：
1. 3x + 5 = 14
解：3x = 14 - 5 → 3x = 9 → x = 3
2. 2y - 7 = 11
解：2y = 11 + 7 → 2y = 18 → y = 9
3. 4z + 9 = 25
解：4z = 25 - 9 → 4z = 16 → z = 4
4. 5a - 8 = 17
解：5a = 17 + 8 → 5a = 25 → a = 5
5. 6b + 12 = 30
解：6b = 30 - 12 → 6b = 18 → b = 3
6. 7c - 15 = 26
解：7c = 26 + 15 → 7c = 41 → c = 41/7
7. 8d + 18 = 50
解：8d = 50 - 18 → 8d = 32 → d = 4
8. 9e - 21 = 45
解：9e = 45 + 21 → 9e = 66 → e = 66/9
9. 10f + 25 = 75
解：10f = 75 - 25 → 10f = 50 → f = 5
10. 11g - 33 = 55
解：11g = 55 + 33 → 11g = 88 → g = 8
11. x/2 + 3 = 8
解：x/2 = 8 - 3 → x/2 = 5 → x = 10
12. y/3 - 4 = 5
解：y/3 = 5 + 4 → y/3 = 9 → y = 27
13. z/4 + 2 = 6
解：z/4 = 6 - 2 → z/4 = 4 → z = 16
14. a/5 - 1 = 3
解：a/5 = 3 + 1 → a/5 = 4 → a = 20
15. b/6 + 5 = 10
解：b/6 = 10 - 5 → b/6 = 5 → b = 30
16. c/7 - 3 = 2
解：c/7 = 2 + 3 → c/7 = 5 → c = 35
17. d/8 + 4 = 7
解：d/8 = 7 - 4 → d/8 = 3 → d = 24
18. e/9 - 2 = 4
解：e/9 = 4 + 2 → e/9 = 6 → e = 54
19. f/10 + 3 = 6
解：f/10 = 6 - 3 → f/10 = 3 → f = 30
20. g/11 - 1 = 2
解：g/11 = 2 + 1 → g/11 = 3 → g = 33
通过以上练习题和答案解析，大家可以逐步熟悉解方程的基本步骤和技巧。希望这些题目能够帮助大家巩固知识，提升解题能力！
