Question

anonymous · Answer

let x be the number of nickels, let y be the number of dimes, since same number of quarters as nickels, x is also the number of quarters

anonymous · Answer

x + y + x =10 total number of coins
0.05x + 0.1y+0.25x=1.65 total value of coins

solving these two equations gives you the number of each coin
