Log3(x+1)=log3(x-1)+1
~~~~~~~~~~~~~~~~~~~~~~~~~~ 

log%283%2C%28x%2B1%29%29 = log%283%2C%28x-1%29%29 + 1  ====>

x + 1 = 3*(x-1)  ====>  x+1 = 3x - 3  ====>  1+3 = 2x  ====>  x = 4%2F2 = 2.


Answer.  x = 2.

Solved.

Log3(x+1)=log3(x-1)+1
----------
log%283%2C%28x%2B1%29%29+=+log%283%2C%28x-1%29%29+%2B+log%283%2C3%29
log%283%2C%28x%2B1%29%29+=+log%283%2C%283%28x-1%29%29%29
x+1 = 3(x-1) = 3x-3
2x = 4
x = 2
