4 * ( 13 - 3Х ) - 17 = - 5X
52 - 12X - 17 = - 5X
12X - 5X = 35
7X = 35
X = 5
-----------------------------
(18 - 3X ) - ( 4 + 2X ) = 10
18 - 3X - 4 - 2X = 10
- 5X = 10 - 14
- 5X = - 4
X = 0,8
------------------------------
14 - X = 0,5 * ( 4 - 2X ) + 12
14 - X = 2 - X + 12
- X + X = 14 - 14
0X = 0
Ответ любые значения переменной Х
-------------------------------
4X - 3 * ( 20 - X ) = 10X - 3 * ( 11 + X )
4X - 60 + 3X = 10X - 33 - 3X
7X - 7X = - 33 + 60
0X ≠ 27
Ответ нет решений
