Bonjour,
Réduire les expressions:
A = 3x - 2z + 7 - x + z
A = 3x - x - 2z + 7 + z
A = 2x - 2z + 7 + z
A = 2x - 2z + z + 7
A = 2x - z + 7
B = 5a - 3b + 1/2 - 10a - 8b + 3/2
B = 5a - 10a - 3b + 1/2 - 8b + 3/2
B = -5a - 3b + 1/2 - 8b + 3/2
B = -5a - 3b - 8b + 1/2 + 3/2
B = -5a - 11b + 1/2 + 3/2
B = -5a - 11b + 4/2
B = -5a - 11b + 2
Bonne journée.
