\n" ); document.write( "\n" ); document.write( "xy=48\r
\n" ); document.write( "\n" ); document.write( "(x+1)(y+1)=63\r
\n" ); document.write( "\n" ); document.write( "xy+x+y+1=63\r
\n" ); document.write( "\n" ); document.write( "48+x+y+1=63
\n" ); document.write( "49+x+y=63
\n" ); document.write( "x+y=63-49
\n" ); document.write( "x+y=14
\n" ); document.write( "-------------------------------------------------------------------------------==
\n" ); document.write( "xy=48\r
\n" ); document.write( "\n" ); document.write( "x+y=14\r
\n" ); document.write( "\n" ); document.write( "which gives answer x=6 and y =8\r
\n" ); document.write( "\n" ); document.write( "check
\n" ); document.write( "6*8 area is 48
\n" ); document.write( "
\n" ); document.write( "let us increase area by 1
\n" ); document.write( "7*9=63 area is increased by 15 \n" ); document.write( "

\n" );
