Seth has 21 nickels

Step-by-step explanation:

Let n represent the number of nickels. Since Seth has 8 more nickels than dimes, then (n-8) is the number dimes.

Nickel is worth 5 cents and dime is worth 10 cents. Thus, n nickels are worth 5n cents and (n-8) dimes are worth 10(n-8) cents. The total value of Seth's coins is $2.35 that is 235 cents, then

5n+10(n-8)=235.

Solve this equation:

$5n+10n-80=235,\\ \\15n=235+80,\\ \\15n=315,\\ \\n=21.$

Step-by-step explanation:

$15 \times 3 = 45 \\ 45 + 1 = 46 \\ 1 \times 10 = 10 \\ 46 + 10 = 56 \\ 56 - 19 = 37 \\ 11 \times 5 = 55 \\ 55 + 37 = 97 \\ 97 - 12 = 80$
