Пошаговое объяснение:

$\frac{x}{32} +1\frac{25}{32} = 2\frac{5}{16}$

$\frac{x}{32} +\frac{57}{32} = \frac{74}{32}$

x+57=74

x=74-57

x=17

$1\frac{5}{7} -\frac{x}{49} = \frac{43}{49}$

$\frac{84}{49} -\frac{x}{49} = \frac{43}{49}$

84-x=43

x=84-43

x=41

$\frac{1}{8} -(\frac{3}{4}-y)=\frac{1}{5} - \frac{1}{10}$

$\frac{1}{8} -\frac{6}{8}+y=\frac{2}{10} - \frac{1}{10}$

$y-\frac{5}{8}= \frac{1}{10}$

$y=\frac{5}{8}+\frac{1}{10}$

$y=\frac{25}{40}+\frac{4}{40}$

y=29/40
