TOTALLY IGNORE the suggestion by that person to CONVERT the decimals to fractions. That doesn't make ANY SENSE, at all!!
\n" );
document.write( "
\n" );
document.write( " ------ Taking log of both sides
\n" );
document.write( "x log (2.5) = (2x + 7) * log (34.1)
\n" );
document.write( "
\n" );
document.write( "
\n" );
document.write( "3.8517(2x + 7) = x ------- Cross-multiplying
\n" );
document.write( "7.7034x + 26.9619 = x
\n" );
document.write( "26.9619 = x - 7.7034x
\n" );
document.write( "26.9619 = - 6.7034x
\n" );
document.write( " \n" );
document.write( "
