5x - 8 = 3x
5x - 3x = 8
2x = 8
x = 8/2
x = 4

4x = 3 - 2x
4x + 2x = 3
6x = 3
x = 3/6
x = 1/2

x = 4x - 6
6 = 4x - x
6 = 3x
6/3 = x
2 = x

Bonjour


5x - 8 = 3x

5x - 3x = 8

       2x = 8

       x = 8/2

       x = 4


 4x = 3 - 2x

4x + 2x = 3

       6x = 3

        x = 3/6

        x = 1/2


 X = 4x - 6

x - 4x = -6

      -3x = -6    

 x = -6/-3

 x = 6/3

 x = 2
