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

-------------------

-14x = 28

x = -28 : 14

x = -2

--------------------

-9x = -36

x = -36 : (-9)

x = 4

-----------------------

5x = -45

x = -45 : 5

x = -9
