To solve this equation, we first need to convert the mixed numbers to improper fractions:

2 3/5 = 13/5
3 2/5 = 17/5

So the equation becomes:

13/5 + 17/5x = 4/15

Now, we can multiply each term by 15 to get rid of the fractions:

15(13/5) + 15(17/5)x = 15(4/15)
195 + 51x = 4
51x = 4 - 195
51x = -191
x = -191/51
x = -3.74

Therefore, the solution to the equation is x = -3.74.
