Немогу брату, подскажите? 1)(39+х)-84=78 2)(х-83)+316=425 3)(600-х)-92=126 х+27-14=36

(39+х)-84=78
39+х=78+84
39+х=162
х=162-39
х=123

(х-83)+316=425
х-83=425-316
х-83=109
х=109+83
х=192

(600-х)-92=126
600-х=126+92
600-х=218
х=600-218
х=382

х+27-14=36
х+27=36+14
х+27=50
х=50-27
х=23

1)(39+х)-84=78

39+x-84=78

x=78-39+84=123

2)(х-83)+316=425

x-83+316 = 425

x=425+83-316 =192

3)(600-х)-92=126

600-x - 92 = 126

-x = 126-600+92 =

-x = -382

x=382

х+27-14=36

x=36-27+14 = 23
