Answer 2

To simplify the expression, let's start by expanding the terms:

4,5(-8y-7) - 3,9(6 - 9y)

Expanding the first term:

= 4,5 * -8y - 4,5 * 7

= -36y - 31.5

Expanding the second term:

= 3,9 * 6 - 3,9 * 9y

= 23.4 - 35.1y

Now, combining the expanded terms:

-36y - 31.5 - 23.4 + 35.1y

Combining like terms:

= (-36y + 35.1y) - (31.5 + 23.4)

= -0.9y - 54.9

So the simplified expression is -0.9y - 54.9.
