Answer 2

To simplify the expression -(6,3a+1,9b) +(0,7b-1,8a)-(1,1b-5,1a), you can perform the operations one step at a time:

1. Start with -(6,3a+1,9b): -(6,3a+1,9b) = (-6, -3a - 1.9b)

2. Then, add (0,7b-1,8a) to the result from step 1: (-6, -3a - 1.9b) + (0,7b-1,8a) = (-6 + 0, -3a - 1.9b + 7b - 1.8a) = (-6, -5.7a + 5.1b)

3. Finally, subtract (1,1b-5,1a) from the result from step 2: (-6, -5.7a + 5.1b) - (1,1b-5,1a) = (-6 - 1, -5.7a + 5.1b - 1b + 5.1a) = (-7, -0.6a + 4.1b)

So, the simplified expression is (-7, -0.6a + 4.1b).
