Question 859248
{{{ln(x + 3) - ln(x - 4) = ln(x)}}}



{{{ln((x + 3)/(x - 4)) = ln(x)}}}



{{{(x + 3)/(x - 4) = x}}}



{{{x + 3 = x(x - 4)}}}



{{{x + 3 = x^2 - 4x}}}



{{{0 = x^2 - 4x - x - 3}}}



{{{0 = x^2 - 5x - 3}}}



{{{x^2 - 5x - 3 = 0}}}

Those are the possible solutions. You need to check each one. I'll let you do this part.
