Answer 2

Let's simplify each expression step by step:

1. 5a + 8a - 7a

Combine like terms (terms with 'a' in them): 5a + 8a - 7a = (5 + 8 - 7)a 5a + 8a - 7a = 6a

So, 5a + 8a - 7a simplifies to 6a.

2. 2a - 3в - 8a + 5 + в

Combine like terms: (2a - 8a) - (3в + в) + 5

Now, simplify each group of like terms: -6a - 4в + 5

So, 2a - 3в - 8a + 5 + в simplifies to -6a - 4в + 5.
