I won't give you the answer, but I will help you through it so you can solve it yourself. From the equation if the price of y increases does Qx increase or decrease? What would you expect Qx to do if x is a complement of y and y's price increases? How about if x is a substitute for y? Please answer these and we'll be happy to check your answers.
If x is a complement of y and y's price increases, Qx will decrease? If x is a substitute of y, then Qx will increase.
Complement?
Are you guessing? Have you figured out what happens to Qx when Py increases?
