You can put this solution on YOUR website!
lets call our positive integer ab. Remember this can be written like this
\n" ); document.write( ":
\n" ); document.write( "10a+b
\n" ); document.write( ":
\n" ); document.write( "a=b+5.....eq 1
\n" ); document.write( "a+b=11....eq 2
\n" ); document.write( ":
\n" ); document.write( "take a's value in eq 1 and plug it into eq 2
\n" ); document.write( ":
\n" ); document.write( "b+5+b=11
\n" ); document.write( ":
\n" ); document.write( "2b=6
\n" ); document.write( ":
\n" ); document.write( "\"highlight%28b=3%29\"
\n" ); document.write( ":
\n" ); document.write( "\"highlight%28a=3%2B5=8%29\"
\n" ); document.write( ":
\n" ); document.write( "our number is 83
\n" ); document.write( "
\n" );
