\n" ); document.write( "The difference between the digits is 1; and the units digit is greater. So

\n" ); document.write( "let x = tens digit
\n" ); document.write( "then x+1 = units digit

\n" ); document.write( "The sum of the digits is then (x)+(x+1) = 2x+1.

\n" ); document.write( "With tens digit x and units digit x+1, the (value of) the number itself is 10(x)+(x+1) = 11x+1.

\n" ); document.write( "The information says the number is 1 more than 5 times the sum of the digits:

\n" ); document.write( " $\"11x%2B1+=+5%282x%2B1%29%2B1\"$

\n" ); document.write( "Solve using basic algebra....

\n" ); document.write( "It is very easy to check your answer in this problem. If the answer you get doesn't check, then you've done something wrong somewhere.

\n" ); document.write( "If the response from the first tutor has not been corrected/revised, it can be educational to look at their work and see where their error is. It's a simple error in setting up the problem -- an error anybody could make if they aren't paying attention. But since their answer of 45 doesn't satisfy the conditions of the problem, you know there is something wrong somewhere.
