You could do this by finding a value that will work and then choose any other pair. That seems a little hard to tell the truth. But if you let x = 1 then every y value will work. Also if you let x =0 then any y value will also work. - 1 = x is a little tricky; I'll let you work on what the values could be.
Any other choice will probably not work. For example if x and y make up a number that will give degrees then x = 30 y = 2 will not work.
30*sin(2) = sin(2*30)
30*sin(2) =? sin(60). Not on this planet.
