.11x+.06(10,000-x)=700
\n" ); document.write( ".11x+600-.06x=700
\n" ); document.write( ".05x=700-600
\n" ); document.write( ".05x=100
\n" ); document.write( "x=100/.05
\n" ); document.write( "x=2,000 invested @ 11%.
\n" ); document.write( "10,000-2,000=8,000 invested @ 6%
\n" ); document.write( "Proof:
\n" ); document.write( ".11*2,000+.06*8,000*700
\n" ); document.write( "220+480=700
