bonjour
3 ( 2 x- 1 ) - 5 x = 3 x - 1
6 x - 3 - 5 x = 3 x - 1
x - 3 = 3 x - 1
x - 3 x = - 1 + 3
- 2 x = 2
x = - 1
3 x + 2 - 4 x - 4 = 3 x + 6 - 10 x - 2
- x - 2 = - 7 x + 4
- x + 7 x = 4 + 2
6 x = 6
x = 1
( - 3 x - 3 / 15 + ( 5 x + 5 ) / 15 = 30 /15
- 3 x - 3 + 5 x = 30
2 x = 30 + 3
2 x = 33
x = 33/2
( 12 - 8 x /24 + ( 9 + 3 x / 24 = ( 18 - 24 x ) /24 + 24 x /24
12 - 8 x + 9 + 3 x = 18 - 24 x + 24 x
- 5 x + 24 x - 24 x = 18 - 12 - 9
- 5 x = - 3
x = 3/5
