I have;

log 2x = log 3+ log (x-1)

and

ln x + ln (x-2) - ln (x+4) = 0

I can not figure out how to separate the variable from the constants.

a\ log 2x = log 3+ log (x-1)

b\ log 3+ log (x-1) - log 2x

c\ (3x-3)/2x

d\ log 3/2 (1-(1/x))

c\ log 3/2 + log (1-(1/x))

this approach doesn't seem to be going any place.
