Use the Distributive Property, which states the following:-
[tex]\bigstar{\bf{a(b+c)=ab+ac}[/tex]
where
we distribute a by multiplying it times b and c
In this case, we should distribute 9:-
9(3x-12)+9x
27x-108+9x
Combine Like Terms:-
[tex]\longrightarrow\sf{36x-108}[/tex]
Hope everything is clear; if you need any clarification/explanation, kindly let me know, and I will comment and/or edit my answer :)
