0,(6)=6/9=2/3
0,(3)=3/9=1/3
3,(6)=3 intregi 6/9=33/9=11/3

2x/3+2x-1/3=4-2x-2+11/3=
2x/3+2x-1/3=2-2x+11/3=
Numitorul comun este 6
4x+12x-2=12-12x+22
16x-2=34-12x
16x+12x=34+2
28x=36
x=36/28

0,(6)x+2x-0,(3)=4-2(x+1)+3,(6)
6/9x+2x-3/9= 4- 2x-2+33/9
2/3*x+2x-1/3=4-2x-2+11/3
2/3*x+4x= 2+12/3
2x+12x=6+12
14x=18
x=18/14
x=9/7
