\n" ); document.write( "Equations:
\n" ); document.write( "f + s = 9000 dollars
\n" ); document.write( "---
\n" ); document.write( "0.05f + 0.06s = -492 dollars
\n" ); document.write( "---------------------------------
\n" ); document.write( "Multiply thru 1st by 5.
\n" ); document.write( "Multiply thru 2nd by 100.
\n" ); document.write( "-------
\n" ); document.write( "5f + 5s = 5*9000
\n" ); document.write( "5f + 6s = 49200
\n" ); document.write( "----------
\n" ); document.write( "Subtract and solve for \"s\":
\n" ); document.write( "s = 4200 (amt. invested at 6%)
