x= cost of one pound bananas
\n" ); document.write( "y= cost of one pound apples
\n" ); document.write( "Total sold
\n" ); document.write( "3.00 x + 2.00 y = 2.40 .............1
\n" ); document.write( "Total value
\n" ); document.write( "4.00 x + 5.00 y = 4.60 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by -5.00
\n" ); document.write( "Multiply (2) by 2.00
\n" ); document.write( "-15.00 x -10.00 y = -12.00
\n" ); document.write( "8.00 x + 10.00 y = 9.20
\n" ); document.write( "Add the two equations
\n" ); document.write( "-7.00 x = -2.80
\n" ); document.write( "/ -7.00
\n" ); document.write( "x = 0.40
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "3.00 x + 2.00 y = 2.40
\n" ); document.write( "1.20 + 2.00 y = 2.40
\n" ); document.write( " 2.00 y = 2.40 -1.20
\n" ); document.write( " 2.00 y = 1.20
\n" ); document.write( " y = 0.60
\n" ); document.write( "x= 0.40 cost of one pound bananas
\n" ); document.write( "y= 0.60 cost of one pound apples
