Best ResponseYou've already chosen the best response.1that was the whole point in pluggin in your first part (x,y)=(6,12)

Best ResponseYou've already chosen the best response.1\[y=\frac{k}{x} \\ xy=k \\ 6(12) =k\]

Best ResponseYou've already chosen the best response.1if you don't you can think of it as 12+12+12+12+12+12 (the sum of six 12's)

Best ResponseYou've already chosen the best response.1ok so when you said 3 you weren't talking about k you were talking about the for x when y=24

Best ResponseYou've already chosen the best response.1\[xy=k \\ 6(12)=k \\ 72=k \\ \text{ yeah } k \text{ is 72} \\ xy=72 \text{ replaced } k \text{ with } 72 \\ \\ \text{ now what is } x \text{ when } y=24 \\ 24x=72 \] yep final answer is x=3 when y=24
