Bonjour,

A = 3x + (-5 + x)

A = 3x - 5 + x

A = 3x + x -5

A = 4x - 5

B = 5 - (-2x + 3)

B = 5 + 2x - 3

B = 2x + 5 - 3

B = 2x + 2

C = x - 3 - (4x + 5)

C = x - 3 - 4x - 5

C = x - 4x - 3 - 5

C = -3x - 8

D = 3 - x + (6 - 5x)

D = 3 - x + 6 - 5x

D = -x - 5x + 3 + 6

D = -6x + 9

Bonne journée :)
