Решите задачу:

$x + 4 \frac{4}{19} = 6 \frac{2}{19 } \\ x = 6 \frac{2}{19} - 4 \frac{4}{19} \\ x = 5\frac{21}{19} - 4 \frac{4}{19 } \\ x = 1 \frac{17}{19}$

$25 - x = 8 \frac{3}{14 } \\ x = 25 - 8 \frac{3}{14 } \\ x = 24 \frac{14}{14} - 8 \frac{3}{14} \\ x = 16 \frac{11}{14}$

$32 - x = 9 \\ x = 32 - 9 \\ x = 23$

$4 \frac{5}{7} - (x - \frac{3}{7} ) = 2 \frac{6}{7} \\ x - \frac{3}{7} = 4 \frac{5}{7} - 2 \frac{6}{7} \\ x - \frac{3}{7} = 3 \frac{12}{7} - 2 \frac{6}{7} \\ x - \frac{3}{7} =1 \frac{6}{7} \\ x = 1 \frac{6}{7} + \frac{3}{7} \\ x = 1 \frac{9}{7} \\ x = 2 \frac{2}{7}$
