\[Пусть\ \text{a\ }и\ b - два\ натуральных\ \]
\[числа,\ сумма\ которых\ \]
\[равна\ 168.\]
\[a = 24n;\ \ b = 24\ m.\]
\[24n + 24m = 168\]
\[24 \cdot (n + m) = 168\]
\[n + m = 168\ :24\]
\[n + m = 7.\]
\[7 = 1 + 6 = 2 + 5 = 3 + 4\]
\[Тогда\ \text{a\ }и\ b:\]
\[a = 24 \cdot 1 = 24;\ \]
\[\ \ b = 24 \cdot 6 = 144\]
\[a = 24 \cdot 2 = 48;\ \ \]
\[b = 24 \cdot 5 = 120\]
\[a = 24 \cdot 3 = 72;\ \]
\[\ b = 24 \cdot 4 = 96.\]
\[Ответ:24\ и\ 144;\ \ 48\ и\ 120;\]
\[\ \ 72\ и\ 96.\]
