12x/9 - 2 = 6x/9 + 11/9 /x9
12x - 18 = 6x +11
12x - 6x = 11 + 18
6x = 29
x = 29/6 = 4,8(3)
12x - 18 = 6x +11
12x - 6x = 11 + 18
6x = 29
x = 29/6 = 4,8(3)
1,(3)x - 2 = 0,(6)x + 1,(2)
(13 - 1)x/9 - 2 = 6x/9 + (12 - 1)/9
12x/9 - 2 = 6x/9 + 11/9 |×9
12x - 2×9 = 6x + 11
12x - 6x = 11 + 18
6x = 29
x = 29/6
x = 4,8(3)
(13 - 1)x/9 - 2 = 6x/9 + (12 - 1)/9
12x/9 - 2 = 6x/9 + 11/9 |×9
12x - 2×9 = 6x + 11
12x - 6x = 11 + 18
6x = 29
x = 29/6
x = 4,8(3)
