Answer:
16/15
Explanation:
To start solving this, you will need a common denominator, an easy one that can be seen is 15. This is a common denominator because both 5 and 3 are factors of it. Because the rule is what you do to one side you have to do to the other, do (5)(8/15) - (3)(8/15), which simplifies to 40/15 - 24/15. Lastly, because the denominators are the same numbers now, just subtract the numerators and get 16/15. Hope this helps and let me know if you have any questions! :)
