I can the company sold 3,00 units in 2008, and 5,00 in 2012
You make 2 2/7 an improper fraction (16/7) and then you subtract 8/7 from 16/7 and you get 1 1/7 (or 8/7) as your final answer
3n/2-n/4=7n+4/12
12 (3n/2-n/4=7n+4/12) factored in 12 to both sides to get rid of fractions
12 (3n/2)-12 (n/4)=12 (7n)+12 (4/12) distributive power
36/2n-12/4n=84n+48/12
18n-3n=84n+4 simplified
15n=84n+4
15n-84n=84n-84n+4 addition property
-69n=4
-69/-69n=-4/69 division property
n=-4/69
Solution : n=-4/69
