Answer 2

To simplify the expression:

• 9,387a - 3,89b + 8,197a - 1,11b - 0,81a

First, group like terms (terms with the same variable) together:

• (9,387a + 8,197a - 0,81a) - (3,89b + 1,11b)

Now, perform the addition and subtraction within each group:

• (16,787a - 0,81a) - (3,89b + 1,11b)

Now, simplify further:

• 15.977a - 4.00b

So, the simplified expression is:

15.977a - 4.00b
