-It has two digits

T for the tens place, U for the ones or units place;
Mark for Tony's score is 10T%2BU.


-The digit in the tens place is 2 more than twice the digit in the ones place.

T=2%2B2U


-The number formed by reversing the order of the digits is 5 more than three times the sum of the digits

10U%2BT=5%2B3%28T%2BU%29

Simplify the second equation and solve the system of the two equations.
