    Answer:

    1000 bills = 7

    500 bills = 19

    Step-by-step explanation:

    x=number of 1000 bills

    y= number of 500 bills

    (you can even invert them, no problem)

    the system is

    x + y = 26

    1000x + 500y = 16500

    therefore

    x=26-y

    using this value in the next equation

    1000*(26-y) + 500y = 16500

    26000 – 1000y + 500y = 16500

    -500y = – 9500

    y=9500/500= 19

    x=26-19= 7
