Answer 2

It seems like you've provided a mathematical expression, but it's a bit unclear. I'll try to interpret it as best as I can, but please let me know if I've misunderstood.

The expression you've given appears to be:

5 - x * 15 - (2 * x) - 2 + 1

Now, let's simplify it step by step:

1. Multiply x by 15: 5 - 15x - (2 * x) - 2 + 1

2. Distribute the negative sign (-) to both terms in parentheses: 5 - 15x - 2x - 2 + 1

3. Combine like terms (the x terms and constants): (-15x - 2x) + (5 - 2 + 1)

4. Simplify the x terms: -17x + 4

So, the simplified expression is:

-17x + 4
