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
