Let’s solve this step by step. :)

First, let’s assign variables for the missing number: x and y.

so the 3 numbers would be x, y and 28

then we have 3 scenarios:
28 + x = 61
28 + y = 76
x + y = 81

Using the first equation, we can get x = 61-28 = 33

Using the 2nd equation, we can get y = 76-28 = 48

then, we can verify if our answer is right by substituting these values in the 3rd equation:

x + y = 81
33 + 48 = 81
81 = 81 ✔️

So the 3 numbers are 28, 33 and 48.
