The correct answer is subtraction and division.

In the equation 36x - 19 = 53, we subtract 19 from both sides to isolate the variable:
36x - 19 - 19 = 53 - 19
36x - 38 = 34

Then, we divide both sides by 36 to solve for x:
(36x - 38) / 36 = 34 / 36
x - 38/36 = 17/18

Therefore, the number of tickets Stacia bought is x = 17/18.
