Решение:

1. \( 15 + 43 - 8 + 8 : 2 + 9 \cdot 5 = 15 + 43 - 8 + 4 + 45 = 58 - 8 + 4 + 45 = 50 + 4 + 45 = 54 + 45 = 99 \)
2. \( 34 + 51 - 24 : 4 \cdot 5 + 23 = 34 + 51 - 6 \cdot 5 + 23 = 34 + 51 - 30 + 23 = 85 - 30 + 23 = 55 + 23 = 78 \)
3. \( 38 + (12 + 8) : 5 + 6 - 8 : 2 = 38 + 20 : 5 + 6 - 4 = 38 + 4 + 6 - 4 = 42 + 6 - 4 = 48 - 4 = 44 \)
4. \( 55 - 3 \cdot 8 + 35 : 5 + 3 \cdot 9 = 55 - 24 + 7 + 27 = 31 + 7 + 27 = 38 + 27 = 65 \)
5. \( 7 \cdot (3 : 3) + (99 - 84) - 4 = 7 \cdot 1 + 15 - 4 = 7 + 15 - 4 = 22 - 4 = 18 \)
6. \( 93 - 44 - 3 \cdot 7 + 47 + 8 + 3 = 93 - 44 - 21 + 47 + 8 + 3 = 49 - 21 + 47 + 8 + 3 = 28 + 47 + 8 + 3 = 75 + 8 + 3 = 83 + 3 = 86 \)
7. \( 7 \cdot 6 + (80 - 42) - 12 : 4 = 42 + 38 - 3 = 80 - 3 = 77 \)
8. \( 17 + 48 : 8 - 72 : 9 + 49 : 7 = 17 + 6 - 8 + 7 = 23 - 8 + 7 = 15 + 7 = 22 \)

Ответ: 99; 78; 44; 65; 18; 86; 77; 22.
