You can put this solution on YOUR website!
Lets assume that,\r
\n" ); document.write( "\n" ); document.write( "x - be the hundreds digit
\n" ); document.write( "3x-1 - be the tens digit
\n" ); document.write( "7x - be the ones digit\r
\n" ); document.write( "\n" ); document.write( "Therefore the number is,\r
\n" ); document.write( "\n" ); document.write( "\"x%2B3x-1%2B7x+=+10\" You get it? The sum of the 3 digits is 10, find x.
\n" ); document.write( "\"11x=11\" Therefore
\n" ); document.write( "\"x=1\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"100%28x%29+%2B+10+%283x-1%29+%2B+1+%287x%29\"\r
\n" ); document.write( "\n" ); document.write( "This is the 3-digit number, hope you get it. We multiply it by 100 for the hundredth digit, ten by tens digit and 1 by ones digit. :) Substitute x now.\r
\n" ); document.write( "\n" ); document.write( "\"%28100%29%281%29%2B10%283%281%29-1%29+%2B+%281%29%287%281%29%29\"
\n" ); document.write( "\"100%2B20%2B7\"\r
\n" ); document.write( "\n" ); document.write( "So the number is 127, check the description.\r
\n" ); document.write( "\n" ); document.write( "Unit digit (7) is 7 times the hundred digit (1)
\n" ); document.write( "Tens Digit (2) is 1 less than 3 times the hundred digits (1)\r
\n" ); document.write( "\n" ); document.write( "Hope that helps! <3\r
