a) $$x - \frac{5}{12} = \frac{2}{12}$$ $$x = \frac{2}{12} + \frac{5}{12}$$ $$x = \frac{7}{12}$$
Ответ:$$\frac{7}{12}$$
б) $$\frac{15}{16} - y = \frac{3}{16}$$ $$y = \frac{15}{16} - \frac{3}{16}$$ $$y = \frac{12}{16} = \frac{3}{4}$$
Ответ: $$\frac{3}{4}$$
в) $$z + \frac{7}{19} = \frac{11}{19}$$ $$z = \frac{11}{19} - \frac{7}{19}$$ $$z = \frac{4}{19}$$
Ответ: $$\frac{4}{19}$$
г) $$\frac{11}{37} - (x - \frac{5}{37}) = \frac{9}{37}$$ $$\frac{11}{37} - x + \frac{5}{37} = \frac{9}{37}$$ $$\frac{16}{37} - x = \frac{9}{37}$$ $$x = \frac{16}{37} - \frac{9}{37}$$ $$x = \frac{7}{37}$$
Ответ: $$\frac{7}{37}$$
д) $$\frac{23}{32} + x - \frac{13}{32} = \frac{27}{32}$$ $$x + \frac{10}{32} = \frac{27}{32}$$ $$x = \frac{27}{32} - \frac{10}{32}$$ $$x = \frac{17}{32}$$
Ответ: $$\frac{17}{32}$$
e) $$\frac{18}{19} - (\frac{8}{19} + \frac{14}{19} - x) = \frac{2}{19}$$ $$\frac{18}{19} - \frac{8}{19} - \frac{14}{19} + x = \frac{2}{19}$$ $$\frac{-4}{19} + x = \frac{2}{19}$$ $$x = \frac{2}{19} + \frac{4}{19}$$ $$x = \frac{6}{19}$$
Ответ: $$\frac{6}{19}$$
