1) Put the log terms together on one side of the equation:
log(7x+1) - log(x-2) = 1
2) Use the relation logA - logB = log(A/B):
log[(7x+1)/(x-2)] = 1
3) Now raise 10 to the power of each side (assuming the logs are base 10):
10^log[(7x+1)/(x-2)] = 10^1
4) Use the relation 10^logA = A and get
(7x+1)/(x-2) = 10
I think you can take it from here.

log (7x+1)=log (x-2)+1
log 7x + log 1=logx-log2+1
-log x +log2 -logx+log2
log 6x + log3=1
log6x +log3-1=0 <----- i think that is ur answer!!

I was amazed by letters, but now they use nature objects, weird.
