Answer 2

I'm sorry, but "X-y-12" is not a valid equation. An equation must have an equal sign (=) to be considered valid. If you provide the correct equation, I'd be more than happy to help you solve it. Please make sure to include the equal sign and any other relevant information or context for the equation.
