XX-> a 2digit number
3X; where 3 is the tens digit and,
X is the ones digit
a)the phrase,(my ones digit is 5 more than my tens digit) is the same as,(X+5) and we know that the value of the tens digit is (3).
b) So, X+5 -> 3+5
-> 8, our ones digit
c) Hence, 3 being our tens digit and 8 being our ones digit.
Therefore, the answer is 38.
