12 nickels

11 dimes

Step-by-step explanation:

Let n = no. of nickels

     d = no. of dimes

   5n = value of nickels in cents

   10d = value of dimes in cents

    170 = total value in cents

(1)   n + d = 23             (2)   5n + 10d = 170

           d = 23 - n                5n + 10(23 - n) = 170

                                           5n + 230 - 10n = 170

                                                     - 5n = - 60

                                                          n = 12 nickels

           d = 23 - 12 = 11 dimes

Check:  12(5) + 11(10) = 60 + 110 = 170 cents or $1.70
