Question

-8/9(-27а-9)+25а-10-2(10+у)+19+3у​

Answer 1

Ответ:

Пошаговое объяснение:

-8/9(-27а-9)+25а-10  = 24a + 8 + 25a - 10 = 49a - 2

-2(10+у)+19+3у​ = -20 - 2y + 19 + 3y = y - 1

Answer 2

To simplify the expression, let's perform the operations step by step:

1. -8/9(-27а-9) Distribute -8/9 to (-27а) and (-9): (-8/9) * (-27а) + (-8/9) * (-9)

   Multiply: 24a - 8

2. 25а - 10 This part can be left as it is.

3. -2(10+у) Distribute -2 to (10+у): -2 * 10 - 2 * у

   Simplify: -20 - 2у

4. 19 + 3у This part can be left as it is.

Now, let's put all the simplified parts together:

(24a - 8) + (25a - 10) + (-20 - 2у) + (19 + 3у)

Next, let's combine like terms:

Combine 'a' terms: (24a + 25a) = 49a Combine constant terms: (-8 - 10 + 19) = 1 Combine 'y' terms: (-2у + 3у) = у

The simplified expression is:

49a + у + 1
