You can put this solution on YOUR website!
the sum of the two digits is 13. --> \"x+%2B+y+=+13\"
\n" ); document.write( "the product of the two digits is 40. --> \"+x%2Ay+=+40\" --> \"y+=+40%2Fx\"
\n" ); document.write( "\"x+%2B+40%2Fx+=+13\"
\n" ); document.write( "\"x%5E2+%2B+40+=+13x+\"
\n" ); document.write( "\"x%5E2+-+13x+%2B+40+=+0\"
\n" ); document.write( "\"%28x-8%29%28x-5%29+=+0\"
\n" ); document.write( "So x is either 8 or 5
\n" ); document.write( "That makes y either 5 or 8 (since their sum must be 13)\r
\n" ); document.write( "\n" ); document.write( "the digit in the ones place is greater than the digit in the tens place.
\n" ); document.write( "So the number is 58
\n" ); document.write( "Check your answer by making sure that 58 satisfies the other conditions.\r
