Bonjour,
a) 2(-3x) = -6x
b) -3(5x) = -15x
c) -3(-2x) = 6x
d) 2x-5+5x-1 = 7x - 6
e) -3x+1-2x-1 = -5x
f) 2x-5+ (1-x) = 2x - 5 + 1 - x = x - 4
g) -(2x+3)-(x+2) = -2x - 3 - x - 2 = -3x - 5
En espérant t'avoir aidé :)

réponses:
a) = -6x
b) = -15x
c) = +6x
d) = -15x
e) = 7x-6
f) 2x-5+ (1-x)
=2x-5+ 0x
=2x-5
g) - (2x+3)-(x+2)
= -2x -3 - (x + 2)
= -2x -3-x-2
= -2x -5 -x
= -3x -5
j’espère t’avoir aidé
