Найдем значения выражений k + 6 и 28 – k при заданных значениях k:
- k = 7:
- k + 6 = 7 + 6 = 13
- 28 – k = 28 – 7 = 21
- k = 8:
- k + 6 = 8 + 6 = 14
- 28 – k = 28 – 8 = 20
- k = 9:
- k + 6 = 9 + 6 = 15
- 28 – k = 28 – 9 = 19
- k = 10:
- k + 6 = 10 + 6 = 16
- 28 – k = 28 – 10 = 18
Ответ: 13 и 21, 14 и 20, 15 и 19, 16 и 18
