Задание 4. Решите уравнения: a) 13 455: x = 65; ; в) (5x+6):3=32 6) с. 16-208

a) 13455 : x = 65

x = 13455 : 65

 13455 | 65
-130   | 207
------
   455
-  455
------
    0

x = 207

б) c ⋅ 16 = 208

c = 208 : 16

  208 | 16
- 16  | 13
------
  48
- 48
------
  0

c = 13

в) (5x + 6) : 3 = 32

5x + 6 = 32 ⋅ 3

5x + 6 = 96

5x = 96 - 6

5x = 90

x = 90 : 5

x = 18

Ответ: a) x = 207; б) c = 13; в) x = 18
