.07x+.05(8,000-x)=496
\n" ); document.write( ".07x+400-.05x=496
\n" ); document.write( ".02x=496-400
\n" ); document.write( ".02x=96
\n" ); document.write( "x=96/.02
\n" ); document.write( "x=4,800 amount invested @ 7%.
\n" ); document.write( "8,000-4,800=3,200 amount invested @ 5%.
\n" ); document.write( "Proof:
\n" ); document.write( ".07*4,800+.05*3,200=496
\n" ); document.write( "336+160=496
