Sagot :

Bonjour

x + 8 = 5

x = 5 - 8

x = - 2

x + 3 = 7

x = 7 - 3

x = 4

x - 36 = 60

x = 60 + 36

x = 96

5x = 20

x = 20/5

x = 4

6x = - 42

x = - 42/6

x = - 7

- 7x = 49

x = - 49/7

x = - 7

6x + 1 = 5

6x = 5 - 1

6x = 4

x = 4/6

x = 2/3

5x + 6 = 11

5x = 11 - 6

5x = 5

x = 5/5

x = 1

3x - 5 = - 2

3x = - 2 + 5

3x = 3

x = 3/3

x = 1

4x - 2 = 2x + 6

4x - 2x = 6 + 2

2x = 8

x = 8/2

x = 4

3x + 1 = 2x + 5

3x - 2x = 5 - 1

x = 4

3x - 4 = 2 - x

3x + x = 2 + 4

4x = 6

x = 6/4

x = 3/2.
