(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I am having trouble finding the right solution to this integral it is of the form int(1/x)dx=lnx+c but apparently im doing it wrong because of the other factors in the denominator

integral(dx/[(k1+k2)x-k2*y]

2. Relevant equations

3. The attempt at a solution

i get (1/(k1+k2))(ln(x/xi))-(x-xi)/k2*y but apparently the answer is

(1/(k2+k2))ln[((k1+k2)x-k2*xi)/((k1+k2)xi-k2*xi)]

so what am i doing wrong
