Evaluate an unknown operator

Question

I have a simple question but I can't seem to be able to solve it.

Given that:

25 ╧ 17 = 267
35 ╧ 23 = 373
45 ╧ 15 = 465

what is 45 ╧ 26?

Thanks. (P.S.: The ╧ operation does not exist, just used in the question and that's all)

Answer 1

This is what I see:

x╧y=10x+y

$${}{}{}{}$$

Answer 2

The answer is $476$ - first number plus first digit of second number concatenated with second digit of second number i.e. $45 + 2, 6$.
