解：d = 12 + 8

d = 20

7. 6e + 10 = 22

解：6e = 22 - 10

6e = 12

e = 12 ÷ 6

e = 2

8. f / 3 - 5 = 1

解：f / 3 = 1 + 5

f / 3 = 6

f = 6 × 3

f = 18

9. g + 12 = 24

解：g = 24 - 12

g = 12

10. 4h - 15 = 13

解：4h = 13 + 15

4h = 28

h = 28 ÷ 4

h = 7

11. i / 5 + 2 = 6

解：i / 5 = 6 - 2

i / 5 = 4

i = 4 × 5

i = 20

12. j - 10 = 20

解：j = 20 + 10

j = 30

13. 7k + 14 = 28

解：7k = 28 - 14

7k = 14

k = 14 ÷ 7

k = 2

14. l / 6 - 3 = 1

解：l / 6 = 1 + 3

l / 6 = 4

l = 4 × 6

l = 24

15. m + 15 = 30

解：m = 30 - 15

m = 15

16. 8n - 20 = 24

解：8n = 24 + 20

8n = 44

n = 44 ÷ 8

n = 5.5

17. p / 7 + 4 = 9

解：p / 7 = 9 - 4

p / 7 = 5

p = 5 × 7

p = 35

18. q - 12 = 18

解：q = 18 + 12

q = 30

19. 9r + 27 = 54

解：9r = 54 - 27

9r = 27

r = 27 ÷ 9

r = 3
