Algebra.Com's Answer #517658 by rothauserc(4718)![]() ![]() You can put this solution on YOUR website! ln(x + 3) – ln(x – 4) = ln(x) \n" ); document.write( "ln [ (x+3) / (x-4) ] = ln(x) \n" ); document.write( "ln [ (x+3) / (x-4) ] - ln(x) = 0 \n" ); document.write( "ln [ ((x+3) / (x-4)) / x ] = 0 \n" ); document.write( "ln [ (x+3) / x(x-4) ] = 0 \n" ); document.write( "now x cannot be less than or equal to 4 since ln is not defined for 0 or negative values, \n" ); document.write( "therefore x must be greater than 4 \n" ); document.write( " \n" ); document.write( " |
