Another algebra 1 question

Let x be a single digit non-zero positive integer and let y be a two digit positive integer. Find all ordered pairs of the form (x,y) such that the sum of x and y and the product of x and y each contain the same digits but in reverse order. Be certain to express all possible answers as ordered pairs of the form (x,y).
