If log M = log N, then M = N, so
Multiply both sides by the common denominator which is 3x:
The second solution is not allowed since the log of negative is not allowed in the real number system.
Final answer:
R^2 at SCC

log (6x + 5) - log 3 = log 2 - log x
log (6x + 5) +log x = log 2+log 3
log ((6x + 5)*x)= log (2*3)
taking the anti log we have
(6x+5)*x = 2*3
6x^2+5x-6 =0
putting it in solution of quadratic equation the solution = .667 and -1.5
since log( -1.5 ) is undefined, only 0.667 is the solution.
