Bonjour pouvez vous m'aidez :)

bonjour

a = 5 +2x+3 = 2x+8

b = 5x-3 +4x= 9x -3

c = x-4-6 = x-10

d = x+2-6x-2 = -5x

e = 3x+1 +x-3 = 4x-2

f = 8x-5x-2+3-4x = -x +1

Bonsoir,

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

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

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

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

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

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