Bonjour ,j'ai besoin d'aide ... pour l'exercice 37 ... svp merci d'avance

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

3x+3 = 3/2
3x = 3/2 - 3/1
3x = 3/2 - 6/2
3x = - 3/ 6
x = (-3/6) / 3

2x-1/6 = 1
2x = 1/1 + 1/6
2x = 6/6
2x = 7/6
x=(7/6) / 2

bonjour

a) x + 1 = 2/3 
    x = 2/3 - 3/3
    x = - 1/3 

b) 3 x + 3 = 3/2
    3 x = 3/2 - 6/2
    3 x = - 4 /2
     x = - 4/2 : 3
     x = - 4/2 * 1/3
     x = - 4/ 6 ou - 2/3     

c) 2 x - 1/6 = 1
    2 x = 1 + 1/6
    2 x = 6/6 + 1/6
     2 x = 7/6
     x = 7/6 : 2
      x = 7/6 * 1/2
      x = 7/12
