bonjour aider moi slvp resoudre les equation suivantes xsur2+x+6sur3egale a 7sur6 6x-3=12 4(x-6)+2x=15 merci

bonjour,

x/2 + x + 6/3 = 7/6

3 x /6 + 6 x /6 + 12/6 = 7/6

3 x + 6 x = 7 - 12

9 x = - 5

x = - 5/9

6 x - 3 = 12

6 x = 12 + 3

6 x = 15

x = 15/6

4 x - 24 + 2 x = 15

6 x = 15 + 24

6 x = 39

x = 39/6 = 6.5
