\n" ); document.write( "Part I 8.00% per annum ---x
\n" ); document.write( "Part II 4.00% per annum ---y
\n" ); document.write( "Total investment
\n" ); document.write( "x + 1 y= 2000 -------------1
\n" ); document.write( "Interest on both investments
\n" ); document.write( "8.00% x + 4.00% y= 132
\n" ); document.write( "Multiply by 100
\n" ); document.write( "8 x + 4 y= 13200.00 --------2
\n" ); document.write( "Multiply (1) by -8
\n" ); document.write( "we get
\n" ); document.write( "-8 x -8 y= -16000.00
\n" ); document.write( "Add this to (2)
\n" ); document.write( "0 x -4 y= -2800
\n" ); document.write( "divide by -4
\n" ); document.write( " y = 700
\n" ); document.write( "Part I 8.00% $ 1300
