The sum of the digits of a two-digit number is 12. The units digit is three times the tens digit. Find the number.\r
\n" ); document.write( "\n" ); document.write( "I think one part of the equation is: x + y = 12\r
\n" ); document.write( "\n" ); document.write( "I think the other part of the equation might be 3 (10x + y)
\n" ); document.write( "Instead of x and y:
\n" ); document.write( "--------------
\n" ); document.write( "t + u = 12 (tens and units)
\n" ); document.write( "u = 3t
\n" ); document.write( "-------
\n" ); document.write( "--> 39
