Bonjour vous pouvez m’aider svp. Merci

A = 5+2x+3 = 8+2x
B = 5x-3+4x = 9x-3
C = x-4-6 = x-10

D = 4x+2-6x-2 = -2x
E = 3x+1+x-3 = 4x-2
F = 8x-5x-2+3-4x = -x+1

Bonjour

A = 5 + (2x + 3)
= 5 + 2x + 3
= 2x + 8

B = 5x - (3 - 4x)
= 5x - 3 + 4x
= 9x - 3

C = (x - 4) - 6
= x - 4 - 6
= x - 10

D = (4x + 2) + (-6x - 2)
= 4x + 2 - 6x - 2
= -2x + 0
= -2x

E = - (-3x - 1) + (x - 3)
= 3x + 1 + x - 3
= 4x - 2

F = 8x - (5x + 2) + (3 - 4x)
= 8x - 5x - 2 + 3 - 4x
= -x + 1

Voilà j'espère avoir pu t'aider ^^
