номера 352 и 353 ПРОШУ...

snshalda Х+12\23=20\23
х=20\23-12\23
х=8\23

31\37-х=16\37
-х=16\37-37\37
х=15\37

х-11\17=3\17
х=3\17+11\17
х=14\17

(12\47+х)-18\47=28\47
12\47+х=28\47+18\47
12\47+х=46\47
х=46\47-12\47
х=34\47

(х-19\32)+15\32=17\32
х-19\2=17\32-15\32
х-19\32=2\32
х=2\32+19\32
х=21\32

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

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

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