Answer:
the correct option is:
Option 1: 6a - 6b
Explanation:
Let's simplify the given expression step by step:
(3a + 2b – 2c) + (2a – 4b – c) + (a – 4b + 3c)
Distribute the terms in each set of parentheses:
3a + 2b - 2c + 2a - 4b - c + a - 4b + 3c
Combine like terms:
(3a + 2a + a) + (2b - 4b - 4b) + (-2c - c + 3c)
6a - 6b + 0c
Simplify the terms with coefficients:
6a - 6b
The simplified expression is 6a - 6b.
