51/3-2 2/3x=3 5/9 решить с проверкой

16/3- 8/3 x = 32/9
-8/3х = 32/9-48/9
-8/3х= -16/9
8/3х=16/9
х=16/9*3/8
х=2/3*2/3*3
Проверка : 16/3- 8/3*2/3= 16*3/3*3- 8*2/3*3=48/9-16/9= 32/9=3 5/9

2 2/3*x=5 1/3-3 5/9=5 3/9-3 5/9=4 12/9-3 5/9=1 7/9
x=1 7/9:2 2/3=16/9*3/8=2/3

5 1/3-2 2/3*2/3=5 1/3-8/3*2/3=5 1/3-16/9=5 1/3-1 7/9=5 3/9-1 7/9=4 12/9-1 7/9=3 5/9
3 5/9=3 5/9
