Answer 2

It seems like you've provided a list of equations, but they are not entirely clear. It appears that you're using different characters, such as "a," "в," and "x," "y," "z," as variables in these equations. However, there might be some confusion with the characters, and some of the equations are not complete or might contain typos.

Let's clarify and solve them one by one:

1. a² - aв = ? This equation seems to be a quadratic equation, but it's not clear what you want to solve for, or if there's a specific value you want to find.

2. xyz - xy = ? Similarly, this equation is not clear about what you want to solve for or the value you are looking for.

3. aв + в = ? It appears to be a linear equation, but it's not clear what you're trying to solve for.

4. 9ab - 3xy = ? This equation is a bit clearer, but you need to specify what you want to solve for (e.g., solving for "a," "b," "x," or "y").

If you provide more context or specify what you want to solve for in these equations, I'll be happy to help you find a solution.
