Réponse :
A = 5 + (2x + 3)
A = 5 + 2x + 3
A = 2x + 8
B = 5x - (3 - 4x)
B = 5x - 3 + 4x
B = 9x - 3
C = (x - 4) - 6
C = x - 4 - 6
C = x - 10
D = (4x + 2) + (- 6x - 2)
D = 4x + 2 - 6x - 2
D = -2x
E = - (-3x - 1) + (x - 3)
E = 3x + 1 + x - 3
E = 4x - 2
F = 8x - (5x + 2) + (3 - 4x)
F = 8x - 5x - 2 + 3 - 4x
F = -x + 1
