What is 2x (-1) 3 (-2) -1x - (-1 - 2)?

To simplify the expression (2x (-1) 3 (-2) - 1x - (-1 - 2)), first calculate (2x (-1) 3 (-2)), which results in (6x). The term (-1x) remains as (-x), and simplifying (-(-1 - 2)) gives (3). Therefore, the entire expression simplifies to (6x - x + 3), which results in (5x + 3).
