Решите уравнение (5/6+x)-2/3=13/18.

\[\left( \frac{5^{\backslash 3}}{6} + x \right) - \frac{2^{\backslash 6}}{3} = \frac{13}{18}\]

\[\frac{5 \cdot 3}{18} + x = \frac{13}{18} + \frac{2 \cdot 6}{18}\]

\[\frac{15}{18} + x = \frac{13}{18} + \frac{12}{18}\]

\[x = \frac{25}{18} - \frac{15}{18}\]

\[x = \frac{10}{18}\]

\[x = \frac{5}{9}\text{.\ }\]
