Ответ:

Пошаговое объяснение:

1)

4x + 15 - 10x = 5 - 11x

-6x + 15 = 5 - 11x

11x - 6x = 5 - 15

5x = -10

x = -10 : 5

x = -2

=============

2)

19 - 6x - 16 = 2x - 37

3 - 6x = 2x - 37

2x + 6x = 3 + 37

8x = 40

x = 40 : 8

x = 5

=========

3)

8x + 21 - 6x = 4x + 3

2x + 21 = 4x + 3

4x - 2x = 21 - 3

2x = 18

x = 18 : 2

x = 9

=========

4)

23 - 12x - 32 = 1 - 17x

-9 - 12x = 1 - 17x

17x - 12x = 1 + 9

5x = 10

x = 10 : 5

x = 2
