Part I 5.00% per annum ------------- Amount invested =x
\n" ); document.write( "Part II 2.00% per annum ------------ Amount invested = y
\n" ); document.write( " 1300
\n" ); document.write( "Interest----- 50
\n" ); document.write( "
\n" ); document.write( "Part I 5.00% per annum ---x
\n" ); document.write( "Part II 2.00% per annum ---y
\n" ); document.write( "Total investment
\n" ); document.write( "x + 1 y= 1300 -------------1
\n" ); document.write( "Interest on both investments
\n" ); document.write( "5.00% x + 2.00% y= 50
\n" ); document.write( "Multiply by 100
\n" ); document.write( "5 x + 2 y= 5000.00 --------2
\n" ); document.write( "Multiply (1) by -5
\n" ); document.write( "we get
\n" ); document.write( "-5 x -5 y= -6500.00
\n" ); document.write( "Add this to (2)
\n" ); document.write( "0 x -3 y= -1500
\n" ); document.write( "divide by -3
\n" ); document.write( " y = 500
\n" ); document.write( "Part I 5.00% $ 800
\n" ); document.write( "Part II 2.00% $ 500
\n" ); document.write( "
\n" ); document.write( "CHECK
\n" ); document.write( "800 --------- 5.00% ------- 40.00
\n" ); document.write( "500 ------------- 2.00% ------- 10.00
\n" ); document.write( "Total -------------------- 50.00
