Bonjour,

A = 5a + 3a + 7b + 6b
A = 8a + 13b

B = 7x + 5y - 3x - 12y
B = 7x - 3x + 5y - 12y
B = 4x - 7y

C = 6x² + 12 + 3x² + 5x + 2x
C = 6x² + 3x² + 5x + 2x + 12
C = 9x² + 7x + 12

D = 9x² - 12x + 7 - 15 - 3x + 4x²
D = 9x² + 4x² - 12x - 3x + 7 - 15
D = 13x² - 15x - 8

E = - (5a + 2b)
E = - 5a - 2b

F = 50 - (- 50 + 10x)
F = 50 + 50 - 10x
F = 100 - 10x
F = - 10x + 100

G = (3a + 2b) + (4a + b)
G = 3a + 2b + 4a + b
G = 3a + 4a + 2b + b
G = 7a + 3b

H = - (11x + 5) + (17x - 6)
H = - 11x - 5 + 17x - 6
H = - 11x + 17x - 5 - 6
H = 6x - 11
