Ln(3x-4)-Ln(x+1)=Ln(2)

My solution:

Ln 3x-4/x+1 =Ln2

3x-4/x+1=2/1

2x+2=3x-4

2=x-4

6=x

**Reiny**, Monday, April 5, 2010 at 4:57pmyes 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
