Answer 2

It seems like you've provided a list of mathematical expressions, but they're not formatted clearly. It's important to use proper mathematical notation to ensure that the expressions are understandable. I'll do my best to interpret what you've written and provide the expressions in a clearer format:

1. $3x + 5(x - 2) - (1 - 3x)$
2. $5(6x - 5) - 5(8x + 1)$
3. $7 - 11x < 9x - 2(5x + 7)$
4. $6 - x > 2(1 - 4x) - 3(1 - 3x)$
5. $3(2x + 13) - 2(x + 2) > 10x - 4$
6. $|3(4x + 9) - 2(x - 1)|$

If you would like me to solve or simplify any of these expressions, please specify which one(s) you'd like to work on.
