bonjour j'ai vraiment besoin d'aide RESOUDRE les equations A = 3 (2x -1) = 2 - ( x -3) C = 8 ( x-2)= 4(2x -4) - 3x

bonsoir

a = 6 x - 3 = 2 - x + 3
a ) 6 x + x = 2 + 3 + 3
     7 x = 8
    x = 8/7

c) 8 x - 16 = 8 x - 16 - 3 x
c = 8 x - 8 x + 3 x = - 16 + 16
c = 3 x = 0
x = 0

A = 3(2x-1) 2 -(x-3)
6x  -3 = 2 -x +3
6x +x = +3 +2 +3
7x = 8
x = 8/7 

C =8(x -2) = 4(2x -4) -3x
8x -16 = 8x -16 -3x 
8 x - 8 x + 3 x = -+16 -16 
3x = 0
x = 0
