Пошаговое объяснение:
-7 + x = -12
x = -12 + 7
x = -5
----------------
-4 - x = -15
x = 15 - 4
x = 11
------------------
x - (-5) = -21
x + 5 = -21
x = -21 - 5
x = -26
---------------
-16 + x = 1
x = 1 + 16
x = 17
-----------------
9 - 3x = -3
3x = 9 + 3
3x = 12
x = 12 : 3
x = 4
---------------------
-2x + 7 = -3
2x = 7 + 3
2x = 10
x = 10:2
x = 5
---------------
-x + 1 = -13
x = 1 + 13
x = 14
============
-6x + 1 = -35
6x = 1 + 35
6x = 36
x = 36:6
x = 6
---------------------
-2x - 1 = -15
2x = 15 - 1
2x = 14
x = 14:2
x = 7
--------------------
-29x - 3 = -32
29x = 32 - 3
29x = 29
x = 1
-----------------------
-4 - 3x = -10
3x = 10 - 4
3x = 6
x = 6 : 3
x = 2
------------------------
-2 - 5x = -12
5x = 12 - 2
5x = 10
x = 10 : 5
x = 2
