I have done the multiplication to get a matrix but I don't know what equations should be produced after that.
I have done it. It was obviously a question few people here could do.
Rather than casting aspersions on the mathematical capability of the many people who give their valuable time and expertise for free helping people, I would suggest that a more accurate observation is that it's a question few people here had the time or inclination to do. (Posting the question in a more appropriate subforum (I've moved it from Pre-algebra to here) might have facilitated getting more responses).
