Решение:
- а) 17x + 50 = 16
- 17x = 16 - 50
- 17x = -34
- x = -34 / 17
- x = -2
- б) 22x - 38 = 6
- 22x = 6 + 38
- 22x = 44
- x = 44 / 22
- x = 2
- в) -46x - 12 = 11
- -46x = 11 + 12
- -46x = 23
- x = 23 / (-46)
- x = -1/2
- г) -38 - 13x = 1
- -13x = 1 + 38
- -13x = 39
- x = 39 / (-13)
- x = -3
Ответ: а) -2; б) 2; в) -1/2; г) -3.
