@aburr If he is using calculator, he knows that x = 10 - 9, but the point he is asking how to operate with Calculator, he just gave the example of simple equation.
@XGenware I know how to make that work with T-84, but not with the sharp scientific calculator thats why I sent the link for manual, I belive you can find a way to solve such equations.
Also, please don't object simply because the author did not respond to your comment. While we understand this is frustrating, unfortunately we cannot force the author to return to the question. Unless you feel you have presented a valid, verifiable solution we'll simply delete the question.
