**Algebra**

ln e^lnx-ln(x-3)=ln8 First of all the "ln of e" cancels out, so it is just: ln(x)-ln(x-3)=ln(8) which is the same as: ln(x/(x-3))=ln(8) e^ both sides... x/(x-3)=8 x=8x-24 7x=24 x=24/7

-52.4576 is the correct answer. ln9^(x+6)=ln7^x (x+6)*ln(9)=x*ln(7) (x+6)/x=ln(7)/ln(9) x/x+6/x=.885622 1+6/x=.885622 6/x=.885622-1 6/x=-.114378 x=6/(-.114378) x=-52.4576
