Best ResponseYou've already chosen the best response.0I don't know what I would get if I did that because I don't know how to divide with a square root or anything like that...

Best ResponseYou've already chosen the best response.1So let's say you have an equation that's 2x=2x. Of course that one is obvious. When you divide by x (you're not supposed to do that because you lose a 0), you get 2=2, which means all solutions work. A little less obvious is 64x=(4^2)*4x. That will also get you 64=64 or x=x depending on which way you divide. This also means all solutions. I think!
