Решение:
\[ 2 \frac{1}{3} = \frac{2 \times 3 + 1}{3} = \frac{7}{3} \]
\[ 2 \frac{1}{2} = \frac{2 \times 2 + 1}{2} = \frac{5}{2} \]
\[ \frac{7}{3} + \frac{x}{5} = \frac{5}{2} \]
\[ \frac{x}{5} = \frac{5}{2} - \frac{7}{3} \]
\[ \frac{x}{5} = \frac{5 \times 3}{2 \times 3} - \frac{7 \times 2}{3 \times 2} \]
\[ \frac{x}{5} = \frac{15}{6} - \frac{14}{6} \]
\[ \frac{x}{5} = \frac{1}{6} \]
\[ x = \frac{1}{6} \times 5 \]
\[ x = \frac{5}{6} \]
Ответ: x = 5/6
