Bonjour !

5+3(2x + 3 ) = 6 - 4( x + 1)

5 + 3*2x + 3*3 = 6 - 4*x - 4*1

5 + 6x + 9 = 6 - 4x - 4

14 + 6x = 2 - 4x

6x + 4x = 2 - 14

10x = -12

x = -1,2

x - 1/6 = x/2​

x - x/2 = 1/6

x/2 = 1/6

x = 1/3

J'espère t'avoir aidé. Bon courage !

Bonjour,

1) 5+3(2x + 3 ) = 6 - 4( x + 1)

5 + 3*2x + 3*3 = 6 - 4*x - 4*1

5 + 6x + 9 = 6 - 4x - 4

14 + 6x = 2 - 4x

6x + 4x = 2 - 14

10x = -12

x = -1,2

2) x - 1/6 = x/2​

x - x/2 = 1/6

x/2 = 1/6

x = 1/3

x = x et X = fois (multiplié)

Voilà ^^ bonne journée :)
