what does it mean when you are solving an equation, and, the variable that you are trying to solve for cancels itself out?

It means that there is no unique value for that variable. It could be anything and the equation would still be valid. Another way of saying this is: "The equation is an identity"

thank you so much that was so helpful i wish i could repay you! since you seem to know what you are doing can you take a look at the more recent question i posted becasue i am getting anxious that nobody else will answer to my comment and im SO stuck on the problems!

I think you are a sweat girl
