bonjour :) j'ai besoin de l'aide pour plusieur equation ! 1 / 4x-5=3x+2 2/ 6x+2=8 3/ 4=5x-6 4/9x=18 5/5x-3=7x-2 6/9x=5x+2 voila j'aurai besoin d'aide silvouplai

4x -5 = 3x +2
4x -3x = +2 +5
x = 7

6x +2 = 8
6x = 8 -2
6x = 6
x = 6/6
x = 1

4 = 5x -6
-5x = -4 -6
-5x = -10
x = -5 / -10
x = 1/2
x = 0,5

5x -3 = 7x -2
5x -7x = -2 +3
-2x = +1
x = 1 / -2
x= -0,5

9x = 5x +2
9x -5x = +2
4x = 2
x = 2 / 4
x= 1 / 2
x = 0,5
