Bonjour,

N = 5 + (2x + 3)

N = 5 + 2x + 3

N = 2x + 8

O = 5t - (3 - 4t)

O = 5t - 3 + 4t

O = 9t - 3

P = 8y - (5y + 2) + (3 - 4y)

P = 8y - 5y - 2 + 3 - 4y

P = 8y - 9y + 1

P = -y + 1

Q = (3 - 4n) - (-2n + 8)

Q = 3 - 4n + 2n - 8

Q = -4n + 2n + 3 - 8 = ................

Tu peux répondre en commentaire je corrigerai

Bonne journée !
