Answer 3

It appears that you have a mathematical expression involving some variables and numbers. However, there seems to be an issue with the use of different decimal separators ("," and "."). To avoid any confusion, I'll assume that you meant to use "." as the decimal separator, as is common in English notation.

Let's simplify the expression:

7.19 + а + (-3.9) + (-5.19) + 3.9

Since we don't have any information about the variable "а," we'll keep it as a variable.

Now, let's combine the numbers:

(7.19 - 5.19) + (3.9 - 3.9) + а

The first two pairs of numbers in parentheses simplify to 2.00 and 0, respectively, leaving us with:

2.00 + 0 + а

Finally, we can simplify further:

2.00 + а

So the simplified expression is "2.00 + а."
