Question

7/8-(х+5/12)=5/24 пжжжжжж (2/15+у)-7/30=1/10

Answer 1

7/8-(х+5/12)=5/24 ;
х+ 5/12= 5/24- 7/8;
х+5/12=5/24-21/24;
х+5/12=-16/24
х= - 16/24 - 5/12
х= - 16/24- 10/24
х=- 1 1/12
Ответ : - 1 1/12

 (2/15+у)-7/30=1/10
2/15 +у=  1/10 + 7/30
2/15 + у= 3/30+7/30
2/15+у= 1/3
у= 1/ 3- 2/15
у= 5/15- 2/15
у= 1/5
Ответ : 1/5
