The value of a "Mint State-63" 1950 Jefferson nickel minted at Denver is 8/7 the value of a 1945 nickel at Philadelphia. Together, the total value of the two coins is $15. What is the value of each coin?

let the value of the '45 nickel be $x
then the Jefferson nickel is worth (8/7)x

x + 8x/7 = 15
7x + 8x = 105
15x = 105
x = 7

take it from there.
