The difference between the digits is 1; and the units digit is greater.  So


let x = tens digit

then x+1 = units digit

NOTE....


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.


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.
