Final answer:
The question is too vague and incomplete to provide a clear answer; it requires further clarification to determine the mathematical values the student is seeking.
Step-by-step explanation:
The question seems to involve finding specific values based on various mathematical relationships or equations. However, the question as presented is unclear, with what appears to be typos and disjointed parts that don't constitute a coherent mathematical problem. Without more context or a clear set of equations or relationships, it is not possible to provide a step-by-step explanation or to find the values requested.
If you can provide a clearer version of the problem, including any relevant equations or relationships between variables like 'a', 'x', and 'y', I would be happy to assist you further. Remember, clarity in the problem statement is crucial in mathematics to ensure that the correct method is used to find the solution.
