a. x + 1 y= 500000\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "b.10.00%x \r
\n" ); document.write( "\n" ); document.write( "c.5.00% y\r
\n" ); document.write( "\n" ); document.write( "d.10.00% x + 5.00% y= 53000\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Total investment
\n" ); document.write( "x + 1 y= 500000 -------------1
\n" ); document.write( "Interest on both investments
\n" ); document.write( "10.00% x + 5.00% y= 53000
\n" ); document.write( "Multiply by 100
\n" ); document.write( "10 x + 5 y= 5300000.00 --------2
\n" ); document.write( "Multiply (1) by -10
\n" ); document.write( "we get
\n" ); document.write( "-10 x -10 y= -5000000.00
\n" ); document.write( "Add this to (2)
\n" ); document.write( "0 x -5 y= 300000
\n" ); document.write( "divide by -5
\n" ); document.write( " y = -60000
\n" ); document.write( "Part I 10.00% $ 560000
\n" ); document.write( "Part II 5.00% $ -60000
\n" ); document.write( "
\n" ); document.write( "CHECK
\n" ); document.write( "560000 --------- 10.00% ------- 56000.00
\n" ); document.write( "-60000 ------------- 5.00% ------- -3000.00
\n" ); document.write( "Total -------------------- 53000.00
