Answer 2

It seems like you have provided an expression with various terms and operators. Let's break it down step by step and simplify it.

The expression you provided is:

4n - m + 3m + n - 20mn² - 15m²n8 - x - 2 + x² + 2x + 4x - 4y + x + 4y - 6x(x - y) - 6x(x + y)b + 3 + b - 1 - 9b - 27 - b² - 3b

Simplifying the expression: Combining like terms and simplifying the expression, we get:

(4n + n) - m + (3m - 15m²n8) - (20mn²) - 4x + x² + (2x + 4x + x) - (4y - 4y) - 6x(x - y) - 6x(x + y)b + (3 - 1) - (9b + b + b² + 3b) - 27

Simplifying further, we have:

5n - m + 3m - 15m²n8 - 20mn² - 4x + x² + 7x - 6x(x - y) - 6x(x + y)b - 1 - 10b - b² - 2b - 27

Now, let's simplify the expression by combining like terms:

5n - m + 3m - 15m²n8 - 20mn² - 4x + x² + 7x - 6x(x - y) - 6x(x + y)b - 1 - 10b - b² - 2b - 27

Simplifying the expression further, we have:

(5n) + (3m - m) - 15m²n8 - 20mn² - 4x + x² + 7x - 6x(x - y) - 6x(x + y)b - 1 - (10b + 2b) - b² - 27

Simplifying more:

5n + 2m - 15m²n8 - 20mn² - 4x + x² + 7x - 6x(x - y) - 6x(x + y)b - 1 - 12b - b² - 27

Finally, we have simplified the expression as much as possible. It is important to note that this is just a simplification and does not solve the equation or provide any specific value for the variables. If you have a specific question or need further clarification, please let me know!
