Bonjour

Explications étape par étape

A = 8- (6x+2)

A = 8 -6x -2

A = -6x +6

B = 7x +(-3x+9)

B = 7x -3x +9

B = 4x +9

C= 3x+ (6x+4)- (3-5x)

C = 3x +6x +4 -3 +5x

C = +14x +1

D = -3(6x-1)

D = -18x +3

E = -3(6x-1) +4(5x+7)

E = -18x +3 +20x +28

E = +2x +31

F= -4(8-5x) +7(-3+6x)

F = -32 +20x -21 +42x

F = +62x -53
