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.
