Answer 2

To simplify the expression, let's first distribute the negative sign to the terms inside the first parentheses:

(9,8c - 7,5d) - (6d - 2,5c) + (6,1c + 8d)

= 9,8c - 7,5d - 6d + 2,5c + 6,1c + 8d

Next, let's combine like terms:

= (9,8c + 2,5c + 6,1c) + (-7,5d - 6d + 8d)

= 18,4c + (-7,5d - 6d + 8d)

= 18,4c - 5,5d

Therefore, the simplified expression is 18,4c - 5,5d.
