Пошаговое объяснение:

2(x + 3) = -12

x + 3 = -12:2

x + 3 = -6

x = -6 - 3

x = -9

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

2x + 3 = x - 1

2x - x = -1 - 3

x = -4

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

5x - 22 = x + 2

5x - x = 2 + 22

4x = 24

x = 24 : 4

x = 6

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

7x + 9 = 2x - 1

7x - 2x = -1 - 9

5x = -10

x = -10 : 5

x = -2

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

4 + 11x = 9x - 14

11x - 9x = -14 - 4

2x = -18

x = -18 : 2

x = -9
