Not sure if I'm doing this right
Ln(3x4)Ln(x+1)=Ln(2)
My solution:
Ln 3x4/x+1 =Ln2
3x4/x+1=2/1
2x+2=3x4
2=x4
6=x

algebra 
Reiny,
yes you are correct, but you must put brackets when typing in this format.
On paper you probably extend the fraction bar over the (x+1) but the way you typed it, it would be understood as
3x  4/x + 1 as 3 separate terms on the left side
