X-Y=5 OR X=Y+5
\n" ); document.write( "X^2-Y^2=136
\n" ); document.write( "(Y+5)^2-Y^2=136
\n" ); document.write( "(Y^2+10Y+25)-Y^2=136
\n" ); document.write( "10Y=136-25
\n" ); document.write( "10Y=111
\n" ); document.write( "Y=111/10
\n" ); document.write( "Y=11.1 ans.
\n" ); document.write( "X=11.1+5=16.1 ANS.
\n" ); document.write( "PROOF:
\n" ); document.write( "16.1^2-11.1^2=136
\n" ); document.write( "259.21-123.21=136
