Let x the larger number and y the other
\n" ); document.write( "then
\n" ); document.write( "x-y=1
\n" ); document.write( "x/7-y/9=1 (x63)
\n" ); document.write( "then
\n" ); document.write( "x-y=1 (-7)
\n" ); document.write( "9x-7y=63
\n" ); document.write( "-7x+7y=-7
\n" ); document.write( "9x-7y=63
\n" ); document.write( "then (doing the addition)
\n" ); document.write( "2x=56
\n" ); document.write( "x=28 and y=27\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
