bjr tlmd je vous souhaite une belle journnée ! je demande de l'aide pr mon exercice svp et mrc

Bonjour,

résoudre :

x + 4 = 6
x = 6 - 4
x = 2

x + 4 = 2
x = 2 - 4
x = -2

x - 4 = 2
x = 2 + 4
x = 6

x - 4 = -2
x = -2 + 4
x = 2

3x = 6
x = 6/3
x = 2

6x = 3
x = 3/6
x = 1/2

x/3 = 6
x = 6 × 3
x = 18

x/6 = 1/3
x = 1/3 × 6
x = 6/3
x = 2

4x + 7 = 15
4x = 15 - 7
x = 8/4
x = 2

4x + 6 = 2x - 4
4x - 2x = -4 - 6
2x = -10
x = -10/2
x = -5

5x + 2 = 9x + 7
2 - 7 = 9x - 5x
4x = -5
x = -5/4

5(x - 3) - 2(x + 4) = (x - 3) + 4(x - 1)
5x - 15 - 2x - 8 = x - 3 + 4x - 4
-2x = -7 + 23
x = 16/-2
x = -8

1/3 (x - 3) - 1/6 (2x + 3) = 7x/2
Je te laisse faire le dernier :)
