Since this was in the last few probs of OG, thot that x/y could also be interpreted as x=-2 and y=-3 and therefore x/y can be equal to 2/3. OG proved me wrong, but is this a theoretical possibility?

we have this law of fraction:

did i get lucky? or can this be a correct approach.

I cross multiplied to get 3x=2y. I then divided by 3 to get 2/3y and just plugged that into where ever x was
