Ответ:

[tex]y=\frac{7}{12}[/tex]

Пошаговое объяснение:

[tex](\frac{15}{36} + y) - \frac{14}{36} = \frac{22}{36} \\\frac{15}{36} + y - \frac{14}{36} = \frac{22}{36} \\\frac{15}{36} + y= \frac{22}{36}+\frac{14}{36}\\\frac{15}{36} + y=\frac{36}{36} \\y=\frac{36}{36}-\frac{15}{36} \\y=\frac{21}{36} = \frac{7}{12}[/tex]
