Answer:
Explanation:
What you are asking is 3n-4=19, where (n)=number. First, you move the 4 over to the other side by adding 4, so now it is 3n=23, then divide by 3 to find out what n equals, or 7 and 2/3, but I am now realizing that is not what you asked, and the answer to your question is 3n-4=19 lol. :)
