\n" ); document.write( "kg x Cashew nuts Php 120
\n" ); document.write( "kg y peanuts Php 40
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "x + y = 80
\n" ); document.write( " 50*(80)=4000
\n" ); document.write( "
\n" ); document.write( "120.00 x + 40.00 y = 4000.00 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -40.00
\n" ); document.write( "Multiply (2) by 1.00
\n" ); document.write( "-40.00 x -40.00 y = -3200.00
\n" ); document.write( "120.00 x 40.00 y = 4000.00
\n" ); document.write( "Add the two equations
\n" ); document.write( "80.00 x = 800.00
\n" ); document.write( "/ 80.00
\n" ); document.write( "x = 10.00
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1.00 x + 1.00 y = 80.00
\n" ); document.write( "10.00 + 1.00 y = 80.00
\n" ); document.write( " 1.00 y = 70.00
\n" ); document.write( " y = 70.00
\n" ); document.write( "Ans x = 10.00
\n" ); document.write( " y = 70.00
\n" ); document.write( " 10.00 kg Cashew nuts
\n" ); document.write( " 70.00 kg peanuts
