Bonsoir

Explications étape par étape

A= -(-2x+2) +3x +9

A = +2x -2 +3x +9

A = 5x +7

B =-6x- (-7x+8) +2

B = -6x +7x -8 +2

B = +x -6

C =( 5x-1) +2-3x

C = 5x -1 +2 -3x

C = 2x +1

D = -5-7x +(2x+2)

D = -5 -7x +2x +2

D = -5x -3

E = -(8x+8) -9x-6

E = -8x -8 -9x -6

E = -17x -14

F= -(4x-9) +3x +8

F = -4x +9 +3x +8

F = -x +17
