Bonjour, je n'arrive pas a faire cet exercice de math pourriez vous m'aider s'il vous plait merci d'avance :)

Bonjour,

(- 9x + 9) / 4 - (3x + 3) / 6 = (- 4x + 1) / 3

(- 27x + 27)/12 - (6x + 6)/12 = (- 16x + 4) / 12

- 27x + 27 - 6x + 6 = - 16x + 4

- 27x - 6x + 16x = 4 - 27 - 6

- 17x = - 29

x = 29/17

4x - 5 (3 - 2x) = 4 - (2x - 7)

4x - 15 + 10x = 4 - 2x + 7

4x + 10x + 2x = 4 + 7 + 15

16x = 26

x = 26/16

x = 13/8

9x - 3 (4 - 3x) = 2 - [35 - 3 (4 - 2x)]

9x - 12 + 9x = 2 - (35 - 15 + 6x)

9x - 12 + 9x = 2 - 35 + 15 - 6x

9x + 9x + 6x = 2 - 35 + 15 + 12

24x = 10

x = 10/24

x = 5/12

5x - 3 [7 - 4 (3 - 2x)] = 5 (3 - x ) - 4

5x - 3 (7 - 12 + 8x) = 15 - 5x - 4

5x - 21 + 36 - 24x = 15 - 5x - 4

5x - 24x + 5x = 15 - 4 + 21 - 36

- 14x = - 4

x = 4/14

x = 2/7

3x - 5 (3 - 2x) = 6 x - 15

3x - 15 + 10x = 6x - 15

3x + 10x - 6x = - 15 + 15

7x = 0

x = 0
