Answer 2

I can help you with your math question. To open the brackets, you need to multiply each term inside the brackets by -7 and keep the signs. For example, -7(a+b-c) = -7a - 7b + 7c. This is the general rule for opening brackets. You can find more examples and explanations on [this website](https://allcalc.ru/node/1826). I hope this helps.
