Пошаговое объяснение:
4) 879 -(458 + x) = 231;
879 - 458 - x = 231
421 - x = 231
x = 421 - 231
x = 190
5) 951 - (x - 354)=882;
951 - x + 354 = 882
1305 - x = 882
x = 1305 - 882
x = 423
6) 549-(425 - x) = 488.
549 - 425 + x = 488
124 + x = 488
x = 488 - 124
x = 364
4) 849-458+х=231
х=231-391
х= -160
5) 951-х+354=882
х=1305-882
х=423
6) 549-425+х=488
х=488-124
х=364
