# intermediate algebra

solve 3+?z-13 = ?z+2

I am posting this as an answer and not as an comment, since I believe a weak point of askSage is the fact that it is too easy to no notice a comment (at least this is what happened to me on several occasions).

I am not sure what you mean by "intermediate algebra", and in fact you did not ask a question.

Is your question "How can one solve an arbitrary equation in one variable numerically (in complex numbers)?" or "How can one solve an arbitrary equation in one variable symbolically?" or "How can one solve an arbitrary linear equation over an arbitrary field?" or "For homework, I have to find z such that 3+z-13=z+2; what is the solution to that equation?"?

The answer will depend on the question.

Hi; your question is vague, to say the least. Are you asking how to use Sage to solve an equation in one variable such as `3+z-13=z+2`? The question marks in your equation might be other characters, but unfortunately they aren't rendering properly; if you put things in backticks they might look better. We'll be better able to serve you if you expand on your question (you should be able to click "edit" to do this).

I could be wrong, but my hunch is that the poster is asking how to solve an algebra homework problem. If so, then it's not a Sage question at all, and is more appropriate to a website like [math.stackexchange.com](http://math.stackexchange.com/) (if any).
