Let N be the number of nickels and D be the number of dimes. Here is what you know:

N = 4D

10D + 5N = 810

-----------------

Now substitute 4D for N

10D + 20D = 810

30D = 810

You take it from there

30D=810 check

=D=810/30 108*.05+27*.1=8.1

=D=27 5.4+2.7=8.1

8.1=8.1

x=y*4

x=27*4

x=108

y=27
