We'll first simplify both sides of the expression to get (simply using the distributive property):
Then, we can simplify a little bit:
To solve for n, we have to isolate it. Let's subtract 3n from both sides to further simplify it:
Then, add 18 to both sides to get the value of n:
And that's your answer. If you have questions on how I got that, feel free to ask!
