To solve the equation, we need to first simplify the expression on the left side of the equation:

8цел1/3 - (5цел2/15 - х) = 3цел2/9

8 (1/3) - (5 (2/15) - х)
= 8/3 - (10/15 - х)
= 8/3 - 2/3 + х
= 6/3 + х
= 2 + х

Now, we substitute this back into the equation:

2 + х = 3цел2/9
2 + x = 6/9
2 + x = 2/3

Now, we solve for x:

x = 2/3 - 2
x = 2/3 - 6/3
x = -4/3

Therefore, the solution to the equation is x = -4/3.
