I will ask for help on solving systems of linear equations but it might be taken off. will it? And what are the questions supposed to ask? a clarification or a tutorial or something else?
Asking for a tutorial is great. Especially if you clearly state what you want to see explained, and possibly what aspects you are having trouble with.
It's very different, however, if you simply post a problem, possibly with additional text asking "what is the answer?" or anything else that could be interpreted to suggest that you're looking for a solution rather than learning how to find the solution yourself.
Some people love such questions and will pretend you asked an interesting question and answer it -- if you're lucky, it might even be the question you meant to ask. Some people even seem to like doing others' homework problems.
Many people strongly dislike the presence of such questions on MSE and will downvote / vote to close it fairly promptly.
