    You can set up a system of equations: .1d + .05n= 2.05 d+n = 29 where d is the number of dimes and n is the number of nickels

    Well, you can take the easier one and solve for one variable and plug it into the other

    so d=29-n

    Then you plug in that d into the other equation so that you have only one variable to get the number of nickels
