I need help solving for x. i am pretty new at this, and not too sure what the first couple steps would be. log6 X + log6 (X-5)=2

Convert the R.H.S. to logarithmic form in base 6. Use addition formula. Drop logs. Have fun solving, because it's all about having fun. In action. log6 X + log6 (X-5)=2 log6 X + log6 (X-5)=log6 36 log6 (X(X-5))=log6 36 Have fun solving.

Thanks for all your help everyone. i think i understand now. at least to do these types of questions ha ha.
