6. A used book store started selling used CDs(x) and videos(y). In the first week, the store sold a combination of 52 CDs and videos. They charged $6 per CD and $9 per video and the total sales were $230. Write the system of equations you would need in order to figure out how many CDs and videos were sold.​

This is what i found “an explicit formula designates the nth term of the sequence, as an expression of n (where n = the term's location). it defines the sequence as a formula in terms of n. this example is an arithmetic sequence(the same number, 5, is added to each term to get to the next term).” i hope this you for what your looking for. can you plz mark me brainliest?

You need to show me the graphs so that i can choose one
