bonjour

2x+3=3x-2

2 x - 3 x = - 2 - 3

- x = - 5

x =  5

-3x+5=6x-7

- 3 x - 6 x = - 7 - 5

- 9 x = - 12

x =  12/9 = 4/3

2(3x-2)=-2x+1

6 x - 4 =  - 2 x + 1

6 x + 2 x = 1 + 4

8 x = 5

x = 5 /8

4x-1/3=-2x+5/2

4 x + 2 x = 5 /2 + 1/3

24 x /6 + 12 x /6 = 15/6 + 2/6

36 x = 17

x = 17/36

Bonjour,

**Cet exercice.

Résoudre les équations:

  • 2x+3= 3x-2

2x-3x= -2-3

-x= -5

x= 5

  • -3x+5=6x-7

-3x-6x= -7-5

-9x= -12

x= -12/-9

x= 12/9

x= 4/3

  • 2(3x-2)=-2x+1

6x-4+2x= 1

8x= 1+4

x= 5/8

  • 4x-1/3=-2x+5/2

4x+2x= 5/2+1/3

6x= (5*3+1*2)/(2*3)

6x= 17/6

6*6x= 17

x= 17/36
