Answer:
x-y=-2 2/3
Step-by-step explanation:
You can't have the exact value of x and y, so we have to iscolate the variables, which means getting rid of the three. You have to divide to both sides three.
(3x-y)/3=8/3, x-y=8/3 then you can simplify into mixed number, which is 2 2/3.
x-y=2 2/3. Hope it helped!
