Verified answer
(305-((45+х)-32))+96=223305-((45+х)-32)=223-96
(45+х)-32=305-127
45+х=178+32
45+х=210
х=210-45
х=165
38+(69-у)+74=172
69-у=172-38-74
69-у=60
у=69-60
у=9
209-((145+х)-12)+96=123
305 -(145+х-12)=123
305-145 -х +12=123
172 - х=123
х=172-123
х=49
(111-(45+х))+96=123
111-45 - х=123 -96
66 - х=27
х=66-27
х=39
