    Dime=10 cents

    nickles=5 cents

    835=10d+5n

    divide both sides by 5

    167=2d+n

    total number of coins is 97

    97=d+n

    we have

    2d+n=167

    d+n=97

    multiply 2nd equation by - 1 and add them

    2d+n=167

    -d-n=97 +

    1d+0n=70

    d=70

    sub back

    d+n=97

    70+n=97

    minus 70 both sides

    n=27

    70 dimes
