oranges ------ x cost
\n" ); document.write( "apples --------y \r
\n" ); document.write( "\n" ); document.write( "4x+5y=2 .............1
\n" ); document.write( "3x+4y=1.56.............2
\n" ); document.write( "multiply (1)by -4
\n" ); document.write( "Multiply (2) by 5
\n" ); document.write( "-16x-20y =-8
\n" ); document.write( "15x+20y= 7.8
\n" ); document.write( "Add the two equations
\n" ); document.write( "-x=-0.2
\n" ); document.write( "/-1
\n" ); document.write( "x= 1/5 =0.20/ Orange
\n" ); document.write( "
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "
\n" ); document.write( "4x+5y=2
\n" ); document.write( "0.8+5y= 2
\n" ); document.write( "5y=2-0.8
\n" ); document.write( "5y=1.2
\n" ); document.write( "y= 1/4= 0.25/Apple
\n" ); document.write( "
\n" ); document.write( " \n" ); document.write( "
