To solve this equation, we need to combine like terms on both sides of the equation.

First, let's simplify the left side of the equation:

2/5 - 3/5y = 3/5 + y
2/5 - 3/5y = 3/5 + 5/5y
2/5 - 3/5y = 8/5y

Now, let's combine like terms on the left side of the equation:

2/5 - 3/5y = 8/5y
2/5 = 11/5y

Now, let's isolate y by multiplying both sides by 5/11:

(5/11) * 2/5 = (5/11) * 11/5y
2/11 = y

Therefore, the solution to the equation is y = 2/11.
