Пошаговое объяснение:

8x - 5 = x - 40

8x - x = -40 + 5

7x = -35

x = -35 : 7

x = -5

9 + 13y = 35 + 26y

26y - 13y = 9 - 35

13y = -26

y = -26 : 13

y = -2

6s + (3s - 2) = 14

6s + 3s - 2 = 14

9s - 2 = 14

9s = 14 + 2

9s = 16

s = 16 : 9

s = 1 7/9

8y - ( 7y - 142) = 51

8y - 7y + 142 = 51

y + 142 = 51

y = 51 - 142

y = -91

(6x + 1) - (3 - 2x) = 14

6x + 1 - 3 + 2x = 14

8x - 2 = 14

8x = 14 + 2

8x = 16

x = 16 : 8

x = 2

(6 - 2c) + 4 = -5c - 3

6 - 2c + 4 = -5c - 3

10 - 2c = -5c - 3

5c - 2c = -3 - 10

3c = -13

c = -13 : 3

c = -4 1/3

(10x - 3) + (14x - 4) = 8 - ( 15 - 22x)

10x - 3 + 14x - 4 = 8 - 15 + 22x

24x - 7 = -7 + 22x

24x - 22x = -7 + 7

2x = 0

x = 0

(7 - 10k) - (8 - 8k) + (10k + 6) = -8

7 - 10k - 8 + 8k + 10k + 6 = -8

8k + 5 = -8

8k = -8 - 5

8k = -13

k = -13 : 8

k = -1,625

6y - 20 = 2(5y - 10) - 4y

6y - 20 = 10y - 20 - 4y

6y - 20 = 6y - 20

6y - 6y = 20 -20

0 = 0

y = (-∞ ; +∞)

6(1 + 5v) = 5(1 + 6v)

6 + 30v = 5 + 30v

30v - 30v = 5 - 6

0 ≠ -1

нет корней

2(h - 3) = 3(4 - h) + 5

2h - 6 = 12 - 3h + 5

2h - 6 = 17 - 3h

2h + 3h = 17 + 6

5h = 23

h = 23 : 5

h = 4,6

3x + 2(2x - 3) = 8 - 7(x + 2)

3x + 4x - 6 = 8 - 7x - 14

7x - 6 = -6 - 7x

7x + 7x = -6 + 6

14x = 0

x = 0

4(3 - 2x) + 24 = 2(3 + 2x)

12 - 8x + 24 = 6 + 4x

36 - 8x = 6 + 4x

4x + 8x = 36 - 6

12x = 30

x = 30 : 12

x = 2,5
