Answer by longjonsilver(2297) (Show Source): You can put this solution on YOUR website!
why x? we use any old letter we care to. Just so happens x is the most common. No reason you need know about :-)

As for your specific questions, i recommend you read through my Lessons on this website and those of rapaljer. Together, I think we cover most topics and we are clear in our help.

5x(3-9x)+4-x
