The sum of a two digit number and the number obtained by reversing the order of its digits is 121. If units and ten’s digit of the number of x and y respectively, then write the linear equation representing the above statement.

Given, sum of a two digit number and the number obtained by reversing the order of its digits is 121


Number is 10y + x


Reverse of the number is 10x + y


10y + x + 10x + y = 121


11x + 11y = 121


x + y = 11
