Ok, so lets evaluate this here:
2/3 (x - 6) - y Let's do the first part: 2/3 (x - 6)
If X = 9 then we subtract 6 from 9 and get 3. Then we multiply
3 by 2/3 and get 2.
Then lets do the 2nd part: 2 - y.
So if y = 5/6, we can first convert 2 into an improper fraction in sixths and have 12/6. Then. we just have to do 12/6 - 5/6 and subtract the numerators and end up with 7/6. The final answer is A, hope this helps!
