Решите уравнение 9/14+(x-3/7)=23/28.

\[\frac{9^{\backslash 2}}{14} + \left( x - \frac{3^{\backslash 4}}{7} \right) = \frac{23}{28}\]

\[\frac{9 \cdot 2}{28} + \left( x - \frac{3 \cdot 4}{28} \right) = \frac{23}{28}\]

\[x - \frac{12}{28} = \frac{23}{28} - \frac{18}{28}\]

\[x = \frac{5}{28} + \frac{12}{28}\]

\[x = \frac{17}{28}\text{.\ }\]
