Pouvez vous m'aider pour cette exercice svp Exercice 8

Bonjour,

1)

x + 8 = 2

x = 2 - 8

x = - 6

2)

- 14x = 7

x = - 7/14

x = - 1/7

3)

- 5x - 2 = 13

- 5x = 13 + 2

- 5x = 15

x = - 15/5

x = - 3

4)

7x + 29 = 3x - 7

7x - 3x = - 7 - 29

4x = 36

x = 36/4

x = 9

5)

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

3 + 12x - 2 = 2x - 1

12x - 2x = - 1 - 3 + 2

10x = - 2

x = - 2/10

x = - 1/5
