\"the sum of the digits of a two-digit number is 6\" ---> t+u=6 ---> t=6-u\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"if the digits are reversed, the new number is three times the original tens digit\" 10u+t=3t\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "10u+t=3t\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "10u=2t\r
