3n-(4n+2)>8=n<-103n(4n+2)>8=n<10

Explanation:

3n-(4n+2)>83n(4n+2)>8

Remove the brackets first:

3n-4n-2>83n4n2>8

Move the n's to one side of the equation and the numbers to the other (change them from positive to negative or vice-versa when you do so):

3n-4n>8+23n4n>8+2

-n>10n>10

Don't forget to change the sign when you multiply by a negative number:

n<-10n<10
