1. Hey guys, I have a question!
When you have algebraic fractions, and you want to get rid of the denominators, I have to times by the denominator of the algebraic fraction(s);you can only do so if its an equation right?? (only if its equal to something?)
2. That is correct because you are multiplying both sides of the equation by whatever the denominator is. If you just have an expression, there are various things you can do but you can't just eject or otherwise rid yourself of the denominator.

That being said, you could probably try to change your variable and get rid of the denominator but working out what that change would have to be might be tricky.
