Пошаговое объяснение:

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

1) 6х - 24 = 0

6x = 24

x = 24/6

x = 4

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

2) 5х - 9 = 6

5x = 6 + 9

5x = 15

x = 15/5

x = 3

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

3) 10х + 1 = 6х

10x - 6x = -1

4x = -1

x = -1/4

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

4) 9х + 6 = 10х

9x - 10x = -6

-x = -6

x = 6

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

5) 6х = х - 2

6x - x = -2

5x = -2

x = -2/5

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

6) 9х - 4 = 10х

9x - 10x = 4

-x = 4

x = -4

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

7) 5х - 3 = - 10х

5x + 10x = 3

15x = 3

x = 3/15

x = 1/5

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

8) х + 9 = - 9х

x + 9x = -9

10x = -9

x = -9/10

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

9) 2х - 7 =6

2x = 6 + 7

2x = 13

x = 13/2

x = 6  1/2

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

10) 2x + 6 = 8

2x = 8 - 6

2x = 2

x = 2/2

x = 1

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

11) 5х - 12 = 13

5x = 13 + 12

5x = 25

x = 25/5

x = 5

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

12) 8х + 14 = 30

8x = 30 - 14

8x = 16

x = 16/8

x = 2

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

13) х + 36 = 72

x = 72 - 36

x = 36

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

14) 12х - 43 = 17

12x = 17 + 43

12x = 60

x = 60/12

x = 5

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

15) - 3х + 9 = 0

- 3x = - 9

x = -9/-3

x = 3

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