Answer 3

I can help you with math problems. To simplify the expression, you need to do the following steps:

- First, distribute the negative sign to each term inside the parentheses. This means changing the sign of each term. For example, -(a+5,1) becomes -a-5,1 and -(-a,-4,9) becomes a+4,9. - Second, remove the parentheses and combine the like terms. Like terms are terms that have the same variable and exponent. For example, -a and a are like terms, and -5,1 and 4,9 are like terms. When you combine them, you get -a-5,1+a+4,9 = -0,2. - Third, write the final answer as -0,2. This is the simplest form of the expression.

Here is a summary of the steps:

-(a+5,1)-(-a,-4,9) = -a-5,1+a+4,9 = -0,2
