I thought that we can solve anything with equations is it always polynomials. Isn't this the same thing as finding the unknown for an equation. As i said in my previous message or am i wrong.

Also what about the rational expressions what are some challenges about working with them?

No, we can solve many other equations. Log and Trig for instance.

Some equations have no known solutions.

Please don't put volunteers name in the subject: a lot of folks who could answer don't bother. What if the ppeople you put in the subject line are gone? You have shot yourself in the foot.
