Answer:
-4x + 5y = 40
Step-by-step explanation:
- move the expression to the left, so you want to get y - 4/5x = 8
- multiply both sides so you get 5y - 4x = 40
- reorder the terms so you get -4x + 5y = 40
personally, I would change the signs afterwards to get 4x - 5y = -40, but the last thing I wrote was what was shown in that picture you sent. hope this helped :)
