Question

How do you combine like terms in `-( 2n + 9) - 6n`?

Answer 1

See a solution process below:

Explanation:

First, remove all of the terms from parenthesis. Be careful to handle the signs of each individual term correctly:

`-2n - 9 - 6n`

Next, group like terms:

`-2n - 6n - 9`

Now, combine like terms:

`(-2 - 6)n - 9`

`-8n - 9`
