Ответ:

1. (127+х)-236=418

127+х-236=418

х=418-127+236

х=527

2. (у-246)+154=300

у-246+154=300

у=300+246-154

у=392

3. (492-а)-87=245

492-а-87=245

492-87-245=а

а=160

4. 745-(b-358)=455

745-b+358=455

745+358-455=b

b=648

5. 304-(543-m)=266

304-543+m=266

m=266-304+543

m=505

6. 789-(x+162)=519

789-x-162=519

789-162-519=x

x=108

Проверка:

1. (127+527)-236=418

418=418

2. (392-246)+154=300

300=300

3. (492-160)-87=245

245=245

4. 745-(648-358)=455

455=455

5. 304-(543-505)=266

266=266

6. 789-(108+162)=519

519=519
