Aidez moi c’est pour la rentrer merci d’avance

Bonjour,

3x= 8

x = 8/3

x-4 = -1

x= -1+4

x= 3

3x+2 = 5

3x = 5-2

3x = 3

x= 3/3

x= 1

x-2 =6x+3

-2 -3 = 6x -x

-5 = 5x

x = -5/5

x= -1

4x-7 = -3x +1

4x+3x = 1 +7

7x = 8

x = 8/7

Bonjour !

a)

[tex]3x = 8 \\ x = \frac{8}{3} [/tex]

b)

[tex]x - 4 = - 1 \\ x = 3[/tex]

c)

[tex]3x + 2 = 5 \\ 3x = 3 \\ x = \frac{3}{3} = 1[/tex]

d)

[tex]x - 2 = 6x + 3 \\ - 5x - 2 = 3 \\ - 5x = 5 \\ x = \frac{5}{ - 5} = - 1[/tex]

e)

[tex]4x - 7 = - 3x + 1 \\ 7x - 7 = 1 \\ 7x = 8 \\ x = \frac{8}{7} [/tex]

Bonne journée
