Answer:


10x+11

Explanation:


\left(-3x-2\right)-\left(7x+9\right)

Apply rule:
\left(a\right)=a


-3x-2-\left(7x+9\right)

Factor out -1:-


-\left(3x+2+\left(7x+9\right)\right)

Apply rule:-
a+\left(b+c\right)=a+b+c


2+\left(7x+9\right)=2+7x+9


=-\left(3x+2+7x+9\right)

Group like terms:-


3x+7x+2+9

Add
2+9=11


3x+7x+11

Add similar elements:-


10x+11
