Решите эти уравнения 700*(83400: m)=420000 (n+10986)*50=589650

83400÷м=420000÷700
83400÷м=600
м=83400÷600
м=139


н+10986=589650÷50
н+10986=11793
н=11793-10986
н=807

700*(83400:м)=420000
83400:м=420000:700
83400:м=600
м=83400:600
м=139
Проверка
700*(83400:139)=420000
700*600=420000
  420000=420000

(n+10986)*50=589650
n+10986=589650^50
n+10986=11793
n=11793-10986
n=807
Проверка
(807+10986)*50=589650
11793*50=589650
    589650=589650
