Answer 1

Ответ:

если это законченный пример то, 7х-6-2у+7а-7b

Answer 2

B) 7(x - 3) + 2(5 - y)

To simplify the expression, let's distribute the coefficients:

7(x - 3) + 2(5 - y) = 7x - 21 + 10 - 2y

Combining like terms:

= 7x - 2y - 11

Therefore, the simplified expression is 7x - 2y - 11.

Ç) 2(a + 2b) - 3(b - 3a) + 5

Distributing the coefficients:

2(a + 2b) - 3(b - 3a) + 5 = 2a + 4b - 3b + 9a + 5

Combining like terms:

= 11a + b + 5

So, the simplified expression is 11a + b + 5.
