Answer 3

It seems like there might be some typos or missing information in the equations you provided. The symbols "×" and "-+=" are not standard mathematical operators, so it's unclear what they represent. Additionally, there seems to be an extra "=" sign in the second equation.

If you can provide the correct equations with clear operators and expressions, I'd be happy to help you solve them. Just make sure to use standard mathematical notation, such as "+", "-", "*", "/", and "=" for equations.
