J’ai besoin d’aide svp Exercice 1: Supprimer les parenthèses :
A = 1 + (2 - x)
B = (2x - 4) + (5x - 6)
C = 3x + (4 - 7x)
D = (7-3x) + (4 - 5x)
E = 5 + (2t + 3)
F = 5t - (3 – 4t)
G = (t - 4) - 6
H = - (-3-1) + (e - 3)
I = (4t +2) + (-6t - 2)
J = 8a - (5a + 2) + (3 - 4a)
K = (x + 3) + (2x - 4)
L = -(8a + 3) -5a
M = (3u + 7) + (-54 + 3)
N = 5w - 6 - (7 - 2w) +4w
P = (3-42) - (-22 + 8)
Q = 4d + (5-70)
R = -(x + 4) + (-2x - 2)
S = 9+ (-22 + 8)
T = 4 + 6f - (-f + 7)
U = 322 - (z + 2) + (4z2-5)
