x Investment in Fund I
\n" ); document.write( "y Investment in Fund II
\n" ); document.write( "Interest calculation in the two repective years.
\n" ); document.write( "0.09x+0.03y= 900...............(1)
\n" ); document.write( "0.10x+0.01y =860...............(2)\r
\n" ); document.write( "\n" ); document.write( "Multiply both equations by 100 to eliminate decimals\r
\n" ); document.write( "\n" ); document.write( "9 x + 3 y = 90000 .............1
\n" ); document.write( "
\n" ); document.write( "10 x + 1 y = 86000 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 1
\n" ); document.write( "Multiply (2) by -3
\n" ); document.write( "9 x 3 y = 90000
\n" ); document.write( "-30 x -3 y = -258000
\n" ); document.write( "Add the two equations
\n" ); document.write( "-21 x = -168000
\n" ); document.write( "/ -21
\n" ); document.write( "x = 8000
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "9 x + 3 y = 90000
\n" ); document.write( "72000 + 3 y = 90000
\n" ); document.write( " 3 y = 90000-72000
\n" ); document.write( " 3 y = 18000
\n" ); document.write( " y = 6000
