Question

решите уравнения
номер 356

Answer 1

429+m=2106        348-k=154          (m+326)-569=674
m=2106-429         k=348-154           m+326=674+569
m=1677                k=194                   m+326=1243
                                                          m=1243-326
                                                          m=917
5084-(k-299)=568
k-299=5084-568
k-299=4516
k=299+4516
k=4815
