Bonjour,

Explications étape par étape:

-3x + 6 = -2x - 5

-3x +2x = -6 -5

-1x = -11

sois -x = -11

x = -11/ -1 = 11

Réponse :

-3x + 6 = -2x - 5

=> -3x + 2x + 6 - 6 = -2x + 2x - 5 - 6

=> -x = -11

Donc, x = 11

Verifiecation l’équation -

-3 (11) + 6 = -2 (11) - 5

=> -33 + 6 = -22 - 5

=> -27 = -27

Donc, x = 11
