I can see why no one answered this question.
It doesn't make any sense!
All you have are two general equations in each case with no stipulations or constraints at all on any of the variables, yet you claim to know what the solutions are.
In both cases you have 2 equations with essentially NINE unknowns. Unless detail is included with future questions like this, no one will ever be able to answer them for you.
Here's a tip, most math 'experts' that answer questions on these kinds of boards, including myself usually do not stop to answer questions that are hopeless...no offense.
So, in the future, unless you just like to post questions and aren't really interested in getting any answers, you need to use standard notation and provide all the pertinent detail and clarity.
So, good luck with your future questions.
