Create Systems of Equations and Inequalities

Daryl has a total of 160 National Football League (NFL) trading cards from both the American Football Conference (AFC) and the National Football Conference (NFC). The number of AFC cards is 8 more than three times the number of NFC cards. Which system of equations can be used to find how many AFC cards, A, and NFC cards, N, Daryl has?

A = 3N
A - 160 = N

A + N = 160
A = 3N + 8

A + N = 160
N = 3A - 8

A - N = 160
N = 3A + 8

Daryl has a total of 160 NFL trading cards

Lets take A represent AFC and N represent NFC 

So total of A & N are 160 which would be given by A + N = 160

And he also mentioned AFC cards are 8 more than 3 times of NFC which means 

A = 8 + 3N
