3*8-14= 80-3*7= 3*(20-17)= 3*(97-92)= 12:2+38= 31+18:2=

Решение:

1. \( 3 · 8 - 14 = 24 - 14 = 10 \)
2. \( 80 - 3 · 7 = 80 - 21 = 59 \)
3. \( 3 · (20 - 17) = 3 · 3 = 9 \)
4. \( 3 · (97 - 92) = 3 · 5 = 15 \)
5. \( 12 : 2 + 38 = 6 + 38 = 44 \)
6. \( 31 + 18 : 2 = 31 + 9 = 40 \)

Ответ: 10, 59, 9, 15, 44, 40.
