Решите задачу:

$2) \frac{31}{37} -x= \frac{15}{37} \\\\x= \frac{31}{37} - \frac{15}{37} \\ \\ x= \frac{16}{37} \\ \\ 3) x- \frac{11}{17} = \frac{3}{17} \\ \\x= \frac{3+11}{17} \\ \\ x= \frac{14}{17}$

$1) \frac{12}{47} +x= \frac{28+18}{47} \\ \\ \frac{12}{47} +x= \frac{46}{47} \\\\x= \frac{46-12}{47} \\ \\ x= \frac{34}{47}$

$2) (x- \frac{19}{32} )+ \frac{15}{32} = \frac{17}{32} \\ \\x- \frac{19}{32} = \frac{17-15}{32} \\ \\x- \frac{19}{32} = \frac{2}{32} \\ \\ x= \frac{2+19}{32} \\ \\ x= \frac{21}{32}$
