Two brothers are saving money to buy tickets to a concert their combined savings is 55. one brother has 15 more than the other. how much has each saved

Let the amount saved by the brother that has less savings be x, then the savings of the other brother is x + 15.

Since their total savings is 55, then
x + x + 15 = 55
2x + 15 = 55
2x = 55 - 15 = 40
x = 40 / 2 = 20

Therefore, one person saved 20 and the other saved 20 + 15 = 35.

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?
