WJarred sells DVDs. His inventory shows that he has a total of 3,500 DVDs. He has 2,342 more contemporary titles than classic titles. Let x represent the number of contemporary titles and y represent the number of classic titles. The system of equations models the given information for both types of DVDs. x + y = 3,500

x – y = 2,342

Solve the system of equations. How many contemporary titles does Jarred have?

2,921 contemporary titles

Step-by-step explanation:

Solve the system by elimination.

Add together the equations, to eliminate y:

Add them together:

2x = 5,842

Divide each side by 2:

x = 2921

So, Jarred has 2,921 contemporary titles
