vous pouvez m'aider svp pour le: I; J; K; L; M; N; O; P; Q mercii​

Bonsoir,

I = -7+4x-9 = 4x - 16

J= 7-2x -1 = -2x +6

K= 3x-8 -4x +7 = -x -1

L = -5x -3 +7x -9 = 2x -12

M= 4x-3+x-4 = 5x -7

N= -4 +2x +2x -4 = 4x -8

O = 6x -12 +12 -6x = 0

P = -12x  +1+35x-45 = 23x -44

Q= 28x +7 -15x -5 = 13x +2
