HELP ASAP!! Adding Linear Expressions. (Add.)

Answer 1

Don't let the parenthesis fool you. Since there is a plus in the middle, you can just combine like terms. Let's do number 1:

$5x+7+x+2$

Combine like terms.

$6x+9$

This is as simple as you can get it. Now, let's do number 2:

$-6x+3+x-7$

Combine like terms.

$-5x-4$

This is as simple as you can get it.

Final Answers:

1.) $6x+9$

2.) $-5x-4$
