Remember that and
usually questions ask for the solution in
Krizalid's solution gives the solution in as it stands now. you may have to do a little tweeqing
look i am at very low level of maths at the moment, the question is only just understandable to me im learning but this type of question at the moment is beyond me i just need the answer
but i also understand your here to teach as well as just tell answers, but at the moment i am not up to the level you can start teaching me
my final admonition: you will never get to the point where you can be taught and you can reason through something if you give up so easily. there is pretty much no one who gets up and understands everything without trying. you must work at it to get it. there are times when i spend hours, even days working on one problem, and i'm sure many of the other helpers here can testify to the same.
