Algebra.Com's Answer #24525 by fractalier(6550) You can put this solution on YOUR website! Okay from \n" ); document.write( "log(6)5 = log(6)(2x+1) - log(6)(3x+4) \n" ); document.write( "we combine to get \n" ); document.write( "log(6)5 = log(6)[(2x+1) / (3x+4)] and then eliminating logs we have \n" ); document.write( "(2x+1) / (3x+4) = 5 \n" ); document.write( "15x + 20 = 2x + 1 \n" ); document.write( "13x = -19 \n" ); document.write( "x = -19/13 \n" ); document.write( "but since that would make log(6)(2x+1) the log of a negative, the answer is NO SOLUTION...poor problem construction actually... \n" ); document.write( " |
