let $x be invested in first fund
\n" ); document.write( "let $y be invested in second fund\r
\n" ); document.write( "\n" ); document.write( "first fund 9%
\n" ); document.write( "the second 3%,
\n" ); document.write( "received 1047$.
\n" ); document.write( "Last year interest equation
\n" ); document.write( "0.09x+0.03y=1047
\n" ); document.write( "multiply by 100
\n" ); document.write( "9x+3y=104700 ...... equation 1
\n" ); document.write( "..
\n" ); document.write( "This year first fund 10%
\n" ); document.write( "second 1%
\n" ); document.write( "received 846$.
\n" ); document.write( "This year interest equation
\n" ); document.write( "0.10x+0.01y=846
\n" ); document.write( "multiply by 100
\n" ); document.write( "10x+y=84600 ......... equation 2\r
\n" ); document.write( "\n" ); document.write( "multiply equation 2 by 3 and subtract1 from it
\n" ); document.write( "30x+3y-9x-3y=253800-104700
\n" ); document.write( "21x=149100
\n" ); document.write( "x= $ 7100 investment in first fund\r
\n" ); document.write( "\n" ); document.write( "..
\n" ); document.write( "10x+y=84600 substitute the value of x
\n" ); document.write( "10*7100+y=84600
\n" ); document.write( "y=84600-71000
\n" ); document.write( "y= $ 13600 investment in second fund.
\n" ); document.write( "
\n" );
