Bonsoirs j'ai ce devoir des math a faire et je n'y arrive pas prouver vous m'aider ? 2(3x-6)=12x-14. Et. 1-5x=2x-4 et. 2-5x=3x-2/3

2(3x - 6) = 12x - 14
6x - 12 = 12x - 14
- 12 + 14 = 12x - 6x
2 = 6x
2/6 = x
1/3 = x

1 - 5x = 2x - 4
1 + 4 = 2x + 5x
5 = 7x
5/7 = x

2 - 5x = 3x - 2/3
2 + 2/3 = 3x + 5x
8/3 = 8x
8 = 24x
8/24 = x
1/3 = x

2(3x-6)=12x-14.
2(3x- 6)= 12x-14
6x - 12 -12x= -14
-6x=-14 +12
-6x=-2
x=2/6
x=1/3


1 - 5x = 2x - 4
1 - 5x = 2x - 4
-5x-2x=-4 -1
-7x=-5
x=5/7


2 - 5x = 3x - 2/3
-5x -3x = -2/3 -2
-8x = -8/3
x= 8/3 x 1/8
x=1/3
