Answer 1

1 столбик                                                                   2 столбик

а)  x=225*15                 в)29*(145-6z)= 203              а) x/16=64                   в)(11z-14)*38=304

     x=3375                      145-6z=203/29                       x=64/16                     11z-14=304/38

б)104у-12=1132             145-6z=7                              б) 72+106y=1344        11z-14=8

104у=1132+12                6z=145-7                                106y=1344-72           11z=14+8

104у=1144                      6z=138                                   106y=1272                 11z=22

у=1144/104                     z=138/6                                   y=1272/106                z=22/11

у=11                                z=23                                       y=12                             z=2

Answer 2

а)
х : 15 = 225
х = 225 * 15
х = 3375
____________
3375 : 15 = 225
225 = 225
б)
104у - 12 = 1132
104у = 1132 + 12
104у = 1144
у = 1144 : 104
у = 11
_______________
104*11 - 12 = 1132
1144 - 12 = 1132
1132 = 1132
в)
29*(145 - 6z) = 203
145 - 6z = 203 : 29
145 - 6z = 7
6z = 145 - 7
6z = 138
z = 138 : 6
z = 23
__________________
29*(145 - 6*23) = 203
29*(145 - 138) = 203
29 * 7 = 203
203 = 203

а)
х : 16 = 64
х = 64 * 16
х = 1024
___________
1024 : 16 = 64
64 = 64
б)
72 + 106у = 1344
106у = 1344 - 72
106у = 1272
у = 1272 : 106
у = 12
________________
72 + 106*12 = 1344
72 + 1272 = 1344
1344 = 1344
в)
(11z - 14) * 38 = 304
11z - 14 = 304 : 38
11z - 14 = 8
11z = 8 + 14
11z = 22
z = 22 : 11
z = 2
_______________________
(11*2 - 14) * 38 = 304
(22 - 14) * 38 = 304
8 * 38 = 304
304 = 304
