    Seperable variables - solve differential eq

    Solve the differential equation. (Use C as an arbitrary constant. Give your answer using the form k - C f(x), where f(x) has been simplified.)

    xy + y' = 130x

    xy + y' = 130x
    So separate the variables:
    y' = -xy + 130x = x(130 - y)

    \frac{dy}{130 - y} = x~dx

    Now integrate both sides.

    Next Steps

    Dan,

    Thanks for the reply. I actually got that far, but am unsure how to get the answer in the format being requested. Any ideas on what the final answer should look like and how you get there?


    Thanks
