Answer:
<em>8 14/45</em>
Step-by-step explanation:
First, place 8/9 anywhere there is a y: 
6+8(8/9-3/5)
Next, do what is in the parenthesis. Make both fractions have the same denominator.
6+8(40/45-27/45)
And now subtract:
6+8(13/45)
Now, multiply 8 and 13/45:
6+ 104/45
Convert the fraction to a mixed fraction:
2 14/45
Finally, add 6:
8 14/45
