Explicación paso a paso:

1* 8x - 8 = - 40

8x = 40 + 8

8x = 48

X = 48 / 8

X = 6

2* - x + 1 = - 7

- X = - 7 - 1

- X = - 8

3* 2x + 2 = 4

2x = 4 - 2

2x = 2

X = 2/2

X= 1

4* 2x + 8 = 16

2x = 16 - 8

2x = 8

X = 8 /2

X = 4

5* - 3x +40 = 10

3x = 10 - 40

3 x = - 30

X = - 30 / 3

X = - 10

6* - x - 8 = 0

- X = 8

7*. -9x - 35 = 10

- 9 x = 10 + 35

- 9 x = 45

X = 45 / - 9

X = - 5

8* - 4 x + 6 = 30

- 4 x = 30 - 6

- 4x = 24

X = 24 / - 4

X = - 6

9* - 8x - 18 = 30

- 8x = 30 + 18

- 8x = 48

X = 48 / - 8

X = - 6

10* - x- 6 = 3

- X = 3 + 6

- X = 9

11* 3 x - 26 = 10

3x = 10 + 26

3x = 36

X = 36 / 3

X = 12

11* 4x - 8 = 8

4x = 8 + 8

4x = 16

X = 16 / 4

X = 4

12 *3x - 5 = - 11

3x = - 11 +5

3 x = - 6

X = - 6 / 3

X = - 2

13* - x + 20 = 31

- X = 31 - 20

- X = 11

14* 6 x - 30 = - 6

6x = - 6 + 30

6x = 24

X = 24 / 6

X = 4

15* - x + 1= 1

- X = 1 - 1

- X = 0

16 * - x + 1 = 0

- X = - 1
