Найдем значения выражений a - 8 и a + 10 при заданных значениях a:
- a = 12:
- a - 8 = 12 - 8 = 4
- a + 10 = 12 + 10 = 22
- a = 20:
- a - 8 = 20 - 8 = 12
- a + 10 = 20 + 10 = 30
- a = 28:
- a - 8 = 28 - 8 = 20
- a + 10 = 28 + 10 = 38
- a = 43:
- a - 8 = 43 - 8 = 35
- a + 10 = 43 + 10 = 53
Ответ: 4 и 22, 12 и 30, 20 и 38, 35 и 53
