    Hi there,

    Hoping that one of you maths wizards can help me out here! I'm trying to self-teach myself C4 and I'm stuck with a question...

    How do I go about finding the general solution of this differential equation by separating the variables? Picture below.

    a^{b-c}=\frac{a^b}{a^c}

    Essentially use the above index rule to split the RHS and solve.

    Use separation of variables:

     \frac{dy}{dx}=e^{x-y}

     \frac{dy}{dx}=\frac{e^{x}}{e^{y}  }
    Just give a hint in future please - the above would have been enough
