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

3*(1/3x - 1/20 - 2/3) = 1/5

Distribute the 3 on the left side:

1x - 3/20 - 2 = 1/5

Combine like terms:

1x - 23/20 = 1/5

Now, we need to isolate x by adding 23/20 to both sides:

1x = 1/5 + 23/20
1x = 4/20 + 23/20
1x = 27/20

Therefore, the solution to the equation is x = 27/20.
