Hello je suis bloquer aidez moi svp ! (Résolution d’équation de premier degré) : -6(x-4)+3 (4x-5)=-3x +7(2-x) 7(x+2)+4 x–5=3 (5— x)+8 Et les deux sur l’image ci

Bonjour

-6(x-4)+3 (4x-5)=-3x +7(2-x)

- 6x + 24 + 12x - 15 = - 3x + 14 - 7x

- 6x + 12x + 3x + 10x = 14 - 24 + 15

19x = 5

x = 5/19

7(x+2)+4 x–5=3 (5— x)+8

7x + 14 + 4x - 5 = 15 - 3x + 8

7x + 4x + 3x = 15 + 8 - 14 + 5

10x = 14

x = 14/10

x = 7/5

x/4 + 2/3 = 7x/6 - 5/3

3x/12 + 8/12 = 14x/12 - 20/12

3x + 8 = 14x - 20

3x - 14x = - 20 - 8

- 11x = - 28

x = 28/11

- 3x/5 - 7/10 = 5x/4 - 1/2

- 12x/20 - 28/20 = 25x/20 - 10/20

- 12x - 28 = 25x - 10

- 12x - 25x = - 10 + 28

- 37x = 17

x = - 17/37.
