1. 85 / х = 17
х=85/17
х=5

2. B*27=459
В=459/27
В=17

3. (х+74)-91=35
х+74=35+91
х+74=126
х=126-74
х=52

4. 54-(х-19)=38
х-19=54-38
х-19=16
х=16+19
х=35

5. х-479=169
х=479+164
х=643

6. 62-(x-23)=34
х - 23 = 62-34
х - 23 = 28
х=28+23
х=51

7. (х+83)-92=45
х+83=45+92
х+83=137
х=137-83
х=54

8. х*43=2451
х=2451:43
х=57
