Answer 2

To simplify the expression -(2+3x)-(9-4x)+(2-3.5x), we'll follow the order of operations (PEMDAS/BODMAS) and combine like terms. Let's break it down step by step:

1. Start by removing the parentheses and distributing the negative sign: -(2+3x) = -2 - 3x -(9-4x) = -9 + 4x +(2-3.5x) = 2 - 3.5x

The expression now becomes: -2 - 3x - 9 + 4x + 2 - 3.5x

2. Combine like terms with similar variables: (-3x + 4x - 3.5x) + (-2 - 9 + 2)

Simplifying the x-terms: (-3x + 4x - 3.5x) = -3x + 4x - 3.5x = -2.5x

Simplifying the constant terms: (-2 - 9 + 2) = -11

The expression now becomes: -2.5x - 11

Therefore, -(2+3x)-(9-4x)+(2-3.5x) simplifies to -2.5x - 11.
