Question

-(-7a-5)-7a Narrow down similar terms​

Answer 1

Ответ:

Пошаговое объяснение:

-(-7a-5)-7a  = 7a + 5 - 7a = 5

-------------------------------------------

3(3a-b)+4(a-b) = 9a - 3b + 4a - 4b = 13a - 7b

Answer 2

To simplify the expression $-(-7a - 5) - 7a$, you can start by distributing the negative sign inside the parentheses:

$-(-7a - 5) - 7a = 7a + 5 - 7a$

Now, you can see that the $7a$ and $-7a$ terms cancel each other out because they have the same coefficient but opposite signs. Therefore, the simplified expression is:

$5$
