Answer:

10 and 13

Step-by-step explanation:

Let the two numbers be p and q.  p = (1/2)q + 8.  p + q = 23.  Substituting (1/2)q + 8 for p, we get (1/2)q + 8 + q = 23.

First, subtract 8 from both sides, obtaining (1/2)q + q = 15.

Next, mult. all terms by 2 to eliminate the fraction (1/2):  q + 2q = 30.

Then 3q = 30, and q = 10.  Then p = (1/2)(10) + 8 = 5 + 8 = 13.

The numbers are 10 and 13.
