Пошаговое объяснение:

8x + 2 = 2x - 22

8x - 2x = -22 - 2

6x = -24

x = -24 : 6

x = -4

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

35 - 6x + 9 = `11x - 10 x + 23 - 7x

44 - 6x = -6x + 23

6x - 6x = 23 - 44

x ≠ -21

нет решений

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

3(x + 1) = 3x

3x + 3 = 3x

3x - 3x = -3

0 ≠ -3

нет решений

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

5x - 2(3x + 2) = x + 20

5x - 6x - 4 = x + 20

-x - 4 = x + 20

x + x = -4 - 20

2x = -24

x = -24 : 2

x = -12

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

-5(x - 3) = 15

-5x + 15 = 15

-5x = 15-15

-5x = 0

x = 0

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

4x(3x + 1) - 3x(4x - 1) = 14

12x² + 4x - 12x² + 3x = 14

7x = 14

x = 14:7

x = 2

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

8(7 - 4x) = 7(4x + 1) - 5(8x - 1) + 24

56 - 32x = 28x + 7 - 40x + 5 + 24

56 - 32x = -12x + 36

32x - 12x = 56 - 36

20x = 20

x = 20:20

x = 1
