Answer:
∛
I am not sure about my answer but I have solved it like this...
Step-by-step explanation:
x-y ÷ ∛x-∛y
we can take ∛ as common and write it outside the parenthesis
∛(x-y)
then we can just cancel out x-y and the answer will be ∛
One equation is a multiple of the other, so you have an infinite solution set and for every x you pick you can find a matching y to fulfill both equations

this forms a line and any of its points is valid in the equation
