(I got your msg. :) )
2%28ln+x%2B+ln+9%29=5
=> ln%28%289x%29%5E2%29+=+5
=> 81x%5E2+=+10%5E5 (I am assuming log to the base 10, Use 'e' instead of 10 if your ques is about natural log)
=> x%5E2=+%2810%5E5%29%2F81
=>+x=+sqrt%28%2810%5E5%29%2F81%29
=> x+=+100%2Asqrt%2810%29%2F9

2(In x+ In 9)=5
It's ln, for natural log, not In.
-------
ln(x) + ln(9) = 2.5
ln(9x) = 2.5
9x+=+e%5E2.5
x+=+e%5E2.5%2F9
-------------------
x =~1.35361
