Question

(2/15+y)-7/6=1/10 чему равен игрик

Answer 1

$- \frac{2}{15} - y - \frac{7}{6} = \frac{1}{10}$

$- y = \frac{1}{10} + \frac{2}{15} + \frac{7}{6} =$

$- y = \frac{3}{30} + \frac{4}{30} + \frac{35}{30}$

$- y = \frac{42}{30}$

$- y = 1 \frac{12}{30}$

$- y = 1 \frac{2}{5}$

$y = - 1 \frac{2}{5}$
