resoudre les equation suivantes a) 2x-1 b) 5x+1=x+4 c) 2-8x=24x-10

a)
2x - 1 = 0
2x = 1
x = 1/2
x = 0,5

b)
5x + 1 = x + 4
5x - x = 4 - 1
4x = 3
x = 3/4
x = 0,75

c)
2 - 8x = 24x - 10
- 8 - 24x = - 10 - 2
- 32x = - 12
x = 12/32
x = 0,375

2x -1
2x = +1
x = 1/2
5x +1 = x +4
5x -x = -1 +4
4x = 3
x = 3/4
2 -8x = 24x -10
-8x -24x = -2 -10
-32x = -12
x = +12/32 = 6/16= 3/8
