Пошаговое объяснение:
-20 - 2x = -29 + x
x + 2x = 29 - 20
3x = 9
x = 9 : 3
x = 3
-----------
18 - 2x - 11 = 2 - 14x - 13
7 - 2x = -11 - 14x
14x - 2x = -11 - 7
12x = -18
x = -18 : 12
x = -1,5
0,2(x - 5) = 4x - 16
0,2x - 1 = 4x - 16
4x - 0,2x = 16 - 1
3,8x = 15
x = 15 : 3,8
x = 3 18/19
-------------
16 - 18x = -25x - 12
25x - 18x = -12 - 16
7x = -28
x = -28 : 7
x = -4
---------------
-17x + 20 = 7x - 28
7x + 17x = 20 + 28
24x = 48
x = 48 : 24
x = 2
Это все,решал сам.
Удачи тебе:3
