Bonjour,
Trouver le nombre x:
1)-2 + 11x = 8x - 5
tu isoles tous les x mais attention au changement de signes
11x-8x= -5+2
3x= -3
x= -3/3
x= -1
2)-2x - 4 = 8 - 6x
-2x+6x= 8+4
tu continues en t'aidant de l'exemple précèdent.

Bonjour,
1)-2 + 11x = 8x - 5
11x - 8x = - 5 + 2
3x = - 3
x = - 3/3
x = - 1
2)-2x - 4 = 8 - 6x
- 2x + 6x = 8 + 4
4x = 12
x = 12/4
x = 3
