Answer:
n= -1
Step-by-step explanation:
distribute 3 to n and -2 which gives you 3n and -6
combine like terms of 9n and 3n which gets you 12
Bring -6 to other side by adding it to both sides. that leaves you with -12
-12 divided by 12 equals -1
Anwser is n= -1
You do distributive property you multiply 3 to n and 3 by -2 and your equation becomes 9n+3n-6=-18. Than you combine like terms and you get 12n-6=-18 and then you add 6 to the -18 and you get -12 and you divide -12 by 12 and you get -1
