Question 269905
THis is a natural log question. we start with
{{{ln x-ln(x-4)=ln 4}}}
step 1 - the rules say that when you subtract ln's you divide the information to get
{{{ln(x)/(x-4) = ln(4)}}}
step 2 - eliminate the ln's to get
{{{x/(x-4) = 4}}}
step 3 - cross multiply to get
{{{x = 4x  - 16}}}
subtract to get
{{{-3x = -16}}}
divide to get
{{{x = 16/3}}}
