Vous pouvez m aider pour l exercice suivant merci

Bonjour !

a.

2x = 6

x = 3

b.

3x = 33

x = 11

c.

9 - x = 4

-x = 4 - 9

-x = -5

x = 5

d.

2x + 6 = 0

2x = -6

x = -3

e.

6 - 3x = 9

-3x = 9 - 6

-3x = 3

x = -1

f.

5x + 2 = x

5x - x = -2

4x = -2

x = -1/2

g.

2(x + 3) = x

2x + 6 = x

2x - x = -6

x = -6

h.

x + 6 = 3(x + 1)

x + 6 = 3x + 3

6 - 3 = 3x - x

3 = 2x

x = 3/2

J'espère t'avoir aidé. Bon courage !
