Answer :
Answer:
[tex]10x+11[/tex]
Step-by-step explanation:
[tex]\left(-3x-2\right)-\left(7x+9\right)[/tex]
Apply rule: [tex]\left(a\right)=a[/tex]
[tex]-3x-2-\left(7x+9\right)[/tex]
Factor out -1:-
[tex]-\left(3x+2+\left(7x+9\right)\right)[/tex]
Apply rule:- [tex]a+\left(b+c\right)=a+b+c[/tex]
[tex]2+\left(7x+9\right)=2+7x+9[/tex]
[tex]=-\left(3x+2+7x+9\right)[/tex]
Group like terms:-
[tex]3x+7x+2+9[/tex]
Add [tex]2+9=11[/tex]
[tex]3x+7x+11[/tex]
Add similar elements:-
[tex]10x+11[/tex]
