There is no two digit number which, when added to Y gives Y.
Let the number be represented as ( x ). The expression for the sum of 10 times the number and 15 added to 11 times the same number can be written as ( 10x + (11x + 15) ). Simplifying this gives ( 21x + 15 ). Therefore, the sum is ( 21x + 15 ).
