.06x+.05(8,000-x)=468
\n" ); document.write( ".06x+400-.05x=468
\n" ); document.write( ".01x=468-400
\n" ); document.write( ".01x=68
\n" ); document.write( "x=68/.01
\n" ); document.write( "x=6,800 amount invested @ 6%.
\n" ); document.write( "8,000-6,800=1,200 amount invested @ 5%.
\n" ); document.write( "Proof:
\n" ); document.write( ".06*6,800+.05*1,200=468
\n" ); document.write( "408+60=468
\n" ); document.write( "468=468
\n" ); document.write( "
