1. Označite prvi broj sa \( x \).

2. Drugi broj je za 8 manji od prvog, pa ga označimo s \( x - 8 \).

3. Navedeni zbroj dvaju brojeva: \( x + (x - 8) = 68 \).

4. Pojednostavite jednadžbu: \( 2x - 8 = 68 \).

5. Dodajte 8 na obje strane jednadžbe: \( 2x = 76 \).

6. Podijelite s 2: \( x = 38 \).

7. Prvi broj je 38, a drugi broj je: \( 38 - 8 = 30 \).

8. Konačno, dva broja su: 38 i 30.
