Bonjour pouvez vous m’aider s’il vous plaît :
Exercice n°3: Résoudre les équations suivantes
x+7=-2
2x-3=5
4-2x=-9
2x+3=-5x+3
-7x-8--10x+3
4x+3=2x+5
-7(x+6)=4-(x-2)
-3x=27
5x+10=-2x+24
-5x+9=-6
x-10=3x+8
5(x-1)-(2x-1)=3-x
-2(2x+1)=-3(x+2)
2-5x=1+6x
9(x-1)=11 x+23
Merci beaucoup

Réponse:

x + 7 = - 2

x = - 9

2x - 3 = 5

x = 4

4 - 2x = 9

x = - 5/2

2x + 3 = - 5x + 3

x = 0

- 7x - 8 = 10x + 3

x = - 11/17

4x + 3 = 2x + 5

x = 1

- 7 ( x + 6 ) = 4 - ( x - 2 )

x = - 8

- 3x = 27

x = - 9

5x + 10 = - 2x + 24

x = 2

- 5x + 9 = - 6

x = 3

x - 10 = 3x + 8

x = - 9

5 ( x - 1 ) - ( 2x - 1 ) = 3 - x

x = 7/4

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

x = 4

2 - 5x = 1 + 6x

x = 1/11

9 ( x - 1 ) = 11 x + 23

x = - 16
