I have a complex equation that is equal to zero with just one unknown that I
have entered as "x". I need to know how to use solver to solve for the
unknown variable. How do I do this? It seems like it should be simple, but
I'm not sure how to enter the unknown into the equation. I keep getting the
error, "Invalid target cell." Which makes me think that I should enter the
unknown into a different cell, or something else. Please help!!!

Assume some value for this x, and then enter this cell as 'by changing
cell'. Your equation cell should be the target cell.

You might be able to use Tools | Goal Seek for your task. See Excel's Help
for info.

(Goal Seek often works fine for a single unknown; Solver is required for
multiple unknowns with constraints.)
