Question

4 X = 12 6+X=12 2x+4=14 3x + 2 =2+10

2 Réponse

  • 4x = 12

    x = 12/4 ou 3

     

     

    6+x = 12

    x = 12-6

    x = 6

     

    2x +4 = 14

    2x = 14-4

    2x = 10

    x= 5

     

    3x+2 = 2+10

    3x = 2+10-2

    3x = 10

    x = 10/3

  • Coucou!!!! 

     

    4x = 12

    x = 12 : 4

    x = 3

     

    6+x = 12

    x = 12-6

    x = 6

     

    2x+4=14

    2x = 14-4

    2x = 10

    x = 10 : 2

    x= 5

     

    3x + 2 = 2+10

    3x = 2+10-2

    3x = 10

    x = 10/3
