take logs of both sides:
\n" ); document.write( "x*log15 = (x+2)*log5,
\n" ); document.write( "xlog15 = xlog5 + 2log5,
\n" ); document.write( "xlog15- xlog5 = 2log5,
\n" ); document.write( "x(log15-log5) = 2log5,
\n" ); document.write( "xlog(15/5) = 2log5,
\n" ); document.write( "xlog3 = 2log5,
\n" ); document.write( "x = 2log5/log3.
\n" ); document.write( " \n" ); document.write( "

\n" );
