Answer 2

To simplify the given expression, let's combine like terms by grouping the variables 'a' and 'b' together:

Starting with the expression: -(2,7a + 1,1b) + (0,8b - 0,5a) - (0,9b - 3,4a)

First, distribute the negative sign in front of the parentheses: -2,7a - 1,1b + 0,8b - 0,5a - 0,9b + 3,4a

Now, let's combine the terms with 'a' and 'b' separately:

Combining the terms with 'a': (-2,7a - 0,5a + 3,4a)

Simplifying: = -2,7a - 0,5a + 3,4a = (3,4a - 0,5a - 2,7a) = 2,9a

Combining the terms with 'b': (-1,1b + 0,8b - 0,9b)

Simplifying: = -1,1b + 0,8b - 0,9b = (-1,1b + 0,8b - 0,9b) = -1,2b

Now we can rewrite the simplified expression as: 2,9a - 1,2b
