aidez moi svp a repondre a ces equations

15x - 17 = 10
15x = 10 + 17
15x = 27
x = 27/15
x = 1,8

- 19x + 13 = 10
- 19x = 10 - 13
- 19x = - 3
x = 3/19

- 9x - 9 = 9
- 9x = 9 + 9
- 9x = 18
x = - 18/9
x = - 2

14x + 17 = 14
14x = 14 - 17
14x = - 3
x = - 3/14

7x - 15 = 16x + 19
7x - 16x = 19 + 15
- 9x = 34
x = - 34/9

5x - 12 = 8x - 6
5x - 8x = - 6 + 12
- 3x = 6
x = - 6/3
x = - 2

19x - 15 = 6x - 19
19x - 6x = - 19 + 15
13x = - 4
x = - 4/13

14x - 8 = 11x - 18
14x - 11x = - 18 + 8
3x = - 10
x = - 10/3
