    Does xk1 mean k1 times x?

    What course is this for? I can think of a number of ways to do this (it is what is called a "linear first order differential equation with variable coefficients") but which would be appropriate for you depends upon what techniques you know.

    xk1 means k1 times x.

    I guess i need the easiest techniques.

    Write it in the form,
    And use the integrating factor method.
