Fund I x
\n" ); document.write( "Fund II ------------ y
\n" ); document.write( "0.08x+0.05y=1330 .............1
\n" ); document.write( "0.12x+0.02y=1500 .............2
\n" ); document.write( "
\n" ); document.write( "multiply (1)by 5
\n" ); document.write( "Multiply (2) by 3
\n" ); document.write( "0.4 x + -0.02 y = 6650
\n" ); document.write( "0.36 x + 0.05 y = 4500
\n" ); document.write( "
\n" ); document.write( "Add the two equations

\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "
\n" ); document.write( "0.08x+0.05y=1330
\n" ); document.write( "1173.68 +0.05y= 1330
\n" ); document.write( "0.05y=1330-1173.68
\n" ); document.write( "0.05y= 156.32
