The sum of the digits of a two-digit number is 4. The ones digit is three times the tens digit. The difference between the digits is two. What is the number?\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 1. Let 3x = ones digit\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 2. Let x = tens digit\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 3. Sum of digits is 4.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3x%2Bx=4\" \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x=1\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3x=3\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 4. Now, check if difference is two.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"3-1=2\" checks out.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 5. ANSWER. The number is 13.\r
\n" ); document.write( "
