There how it goes:
1) First we need to do something with , which confused me, when I tried to solve it by myself. We need to get it in the form of and somehow. Well, is equal to , and we can add and substract 1. Therefore:
Here we go
Now, let and , and express everything in terms of x and y:
By definition , and , therefore:
And the answer is:
