a) 3x-7=5x+g b) 8(x-2)=4(2x-4)-3x c) 3(2x-1)=2-(x-3) d) g+2x=14+3x e) 2(x-3)=16 f) x . _. = -5 . tres urgent svp aider moi sa fais 1 semaine que j'essaye de le

bonsoir

a)
3 x - 5x =  9 +7
- 2x = 16
x = -16/2 = - 8

b)
8x -16 = 8x -16 - 12 x
8 x - 8 x +12x = - 16 +16
12 x = 0
x = 0

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


d)
2x - 3x = 14 - 9
- x = 5
x = -5

e)
 2(x-3)=16
2x - 6 = 16
2 x = 16 +6
2x = 22
x = 11
