Answer 3

Let's simplify the expression step by step:

2(a + 2b) - 3(b - 4c) - (2a + b - 5c)

First, distribute the coefficients:

2a + 4b - 3b + 12c - 2a - b + 5c

Combine like terms:

(2a - 2a) + (4b - 3b - b) + (12c + 5c)

The terms with the same variables can be combined:

0a + 0b + 17c

Simplifying further:

0 + 0 + 17c

The expression simplifies to:

17c
