решите уравнения: (24-x)+37=49 (214-7c)*42=5460 25*(328-8k)=5400 (11*z-14)*38=304 (10Z-68)/6=2

Ответы:

24-х =12

х=24-12

х=12

это первое

24-х= 49-37        214-7с=5460:42      328-8к=5400:25     11z-14=304:38     10z-68=2*6

24-х=12              214-7с=130              328-8к=216            11z-14=8              10z=68+12

х=24-12              7с=214-130              8к=328-216             11z=8+14             z=80:10

х=12                    7с=84                       8к=112                    11z=22                 z=8

                            с=84:7                       к=112:8                  z=22:11

                            с=12                          к=14                        z=2
