Решить уравнения: 1) (x - 7 3/16) - 4 5/16 = 2 9/16; 2) 3 7/17 - (x - 1 4/17) = 1 9/17; 3) 5 10/12 - (x - 2 7/12) = 1 3/12; 4) (x - 7 3/18) + 5 5/18 = 12 9/18

1) $(x - 7 \frac{3}{16}) - 4 \frac{5}{16} = 2 \frac{9}{16}$ $x - 7 \frac{3}{16} = 2 \frac{9}{16} + 4 \frac{5}{16}$ $x - 7 \frac{3}{16} = 6 \frac{14}{16}$ $x = 6 \frac{14}{16} + 7 \frac{3}{16}$ $x = 13 \frac{17}{16} = 14 \frac{1}{16}$ **Ответ:** $14 \frac{1}{16}$ 2) $3 \frac{7}{17} - (x - 1 \frac{4}{17}) = 1 \frac{9}{17}$ $x - 1 \frac{4}{17} = 3 \frac{7}{17} - 1 \frac{9}{17}$ $x - 1 \frac{4}{17} = 2 \frac{24}{17} - 1 \frac{9}{17} = 1 \frac{15}{17}$ $x = 1 \frac{15}{17} + 1 \frac{4}{17}$ $x = 2 \frac{19}{17} = 3 \frac{2}{17}$ **Ответ:** $3 \frac{2}{17}$ 3) $5 \frac{10}{12} - (x - 2 \frac{7}{12}) = 1 \frac{3}{12}$ $x - 2 \frac{7}{12} = 5 \frac{10}{12} - 1 \frac{3}{12}$ $x - 2 \frac{7}{12} = 4 \frac{7}{12}$ $x = 4 \frac{7}{12} + 2 \frac{7}{12}$ $x = 6 \frac{14}{12} = 7 \frac{2}{12} = 7 \frac{1}{6}$ **Ответ:** $7 \frac{1}{6}$ 4) $(x - 7 \frac{3}{18}) + 5 \frac{5}{18} = 12 \frac{9}{18}$ $x - 7 \frac{3}{18} = 12 \frac{9}{18} - 5 \frac{5}{18}$ $x - 7 \frac{3}{18} = 7 \frac{4}{18}$ $x = 7 \frac{4}{18} + 7 \frac{3}{18}$ $x = 14 \frac{7}{18}$ **Ответ:** $14 \frac{7}{18}$
