I am having difficulty making x the subject of the following formula.(adsbygoogle = window.adsbygoogle || []).push({});

y = [a.e^(b.x)] + [c.e^(d.x)]

I thought the first step would be to take the natural log of both sides of the equation:

ln(y) = ln(a)+b.x+ln(c)+d.x

But this does not work, even though the following is correct:

y = a.e^x

ln(y) = ln(a) + x

I am a little stuck as to what to try next!
