\n" ); document.write( "Equations:
\n" ); document.write( "Quantity: x + y = 20,000
\n" ); document.write( "Interest0.06x+0.09y = 14000
\n" ); document.write( "----------------------------------
\n" ); document.write( "Multiply thru 1st by 6
\n" ); document.write( "Multiply thru 2nd by 100
\n" ); document.write( "----------------------------------
\n" ); document.write( "6x + 6y = 6*20000
\n" ); document.write( "6x + 9y = 1400000
\n" ); document.write( "---------------------------
\n" ); document.write( "Subtract and solve for \"y\":
\n" ); document.write( "3y = 20000
\n" ); document.write( "y = $6,666.66 (amt. invested at 6%)
\n" ); document.write( "---
\n" ); document.write( "Solve for \"x\":
\n" ); document.write( "x + y = 20,000
\n" ); document.write( "y = 13,333.34 (amt. invested at 9%\r
