svp c'est pour demain !! merci d'avance ! Réduis A = 8x +3 - (6x + 2) B = (9x + 5) + (-2x + 3) C = (4x - 9) - (2x - 7) A = B = . C =....... D=. E = ...... H= D = (9x + 5) - 2x + 3 E = (4x - 9) - 2x + 7 H = 8x + 3 - 6x-2​

Bonjour,

Réduire:

A = 8x +3 - (6x + 2) = 8x+3-6x-2= 2x+1

B = (9x + 5) + (-2x + 3) = 9x+5-2x+3= 7x+8

C = (4x - 9) - (2x - 7) = 4x-9-2x+7= 2x-2

D = (9x + 5) - 2x + 3 = 9x+5-2x+3= 7x+8

E = (4x - 9) - 2x + 7 = 4x-9-2x+7= 2x-2

H = 8x + 3 - 6x-2​= 2x+1
