let each apple cost x
\n" ); document.write( "each orange cost y
\n" ); document.write( "..
\n" ); document.write( "4x+2y=1...................1
\n" ); document.write( "2x+3y = 0.70..............2
\n" ); document.write( "..
\n" ); document.write( "multiply (2) by -2
\n" ); document.write( "-4x-6y=-1.40
\n" ); document.write( "add this to (1)
\n" ); document.write( "4x-4x+2y-6y=1-1.40
\n" ); document.write( "-4y=-0.4
\n" ); document.write( "/-4
\n" ); document.write( "y=-0.4/-4
\n" ); document.write( "y=0.1 = 10 cents cost of orange
\n" ); document.write( "plug value of y in (1)
\n" ); document.write( "4x+2y=1
\n" ); document.write( "4x+2*0.1=1
\n" ); document.write( "4x+0.2=1
\n" ); document.write( "-0.2
\n" ); document.write( "4x=1-0.2
\n" ); document.write( "4x=0.8
\n" ); document.write( "/4
\n" ); document.write( "x=0.8/4
\n" ); document.write( "x=0.2= 20 cents = cost of apple
\n" ); document.write( "...
