The Attempt at a Solution

I just need to know how to proceed with the problem. Not the answer. This is the scan of my attempt.

I stuck about how i eliminate the x and y terms. I thought replacing it with GP series sum would help but it unnecessarily introduces a restriction on x and y.

Is the initial process in my worked out solution correct?
if not what direction do you suggest ?

I suggest posting this in the 'calculus & beyond' section. This definitely does not belong under the rubric 'introductory physics'.

I have to say that every time somebody links to an image which contains the problem statement and solution, I ignore the post.

Well not everyone is comfortable with latex and well some equations are just easier to write out. Each to his own I guess. Ill type them out if i can
