To solve the equation, we first need to simplify each term:

1) 2 1/7 = 15/7
2 1/3 = 7/3
1 2/5 = 7/5

2) 2 1/3x = 7/3x
1 2/5 = 7/5

Now we can substitute these values back into the equation and simplify:

2(15/7) - 2(7/3)x - 2(7/5) - 3(2x) + 3 = 9
30/7 - 14/3x - 14/5 - 6x + 3 = 9
30/7 - 14/3x - 14/5 - 6x + 3 - 9 = 0
30/7 - 74/15 - 6x + 3 - 9 = 0
(450 - 1480 - 42x + 105 - 315) / 105 = 0
(-845 - 42x - 210) / 105 = 0
-42x - 1055 = 0
-42x = 1055
x = -1055/42
x = -25

Therefore, the solution to the equation is x = -25.
