.05x+.04(4,500-x)=210
\n" ); document.write( ".05x+180-.04x=210
\n" ); document.write( ".01x=210-180
\n" ); document.write( ".01x=30
\n" ); document.write( "x=30/.01
\n" ); document.write( "x=3,000 amount invested @ 5%.
\n" ); document.write( "4,500-3,000=1,500 amount invested @ 4%.
\n" ); document.write( "Proof:
\n" ); document.write( ".05*3,000+.04*1,500=210
\n" ); document.write( "150+60=210
\n" ); document.write( "210=210
\n" ); document.write( "
