Bonsoir, j'aurais besoin d'aide pour cet exercice de Maths svp. Voici l'énoncé:
Supprimer les parenthèses, puis réduire:
G= -7 + (3x-5)
H= x - (2-7x)
I= 6-5x + 3x - (4-6x) + 5 + (7-2x)
J= 4n + (1 + 3n)
K= 8m + 4 - (-2m-5)
L= x-8 - (2 + 4x - (9-5x))
Merci d'avance pour les réponses.

Verified answer
G = -7+3x-5 = 3x-12
H = x-2+7x = 8x-2
I = 6-5x+3x-4+6x+5+7-2x = 2x+14
J = 4n+1+3n = 7n+1
K = 8m+4+2m+5 = 10m+9
L = x-8-(2+4x-9+5x)
L = x-8-(9x-7)
L = x-8-9x+7 = -8x-1
