Question

РЕШИТЕ УРАВНЕНИЯ !!!
1. 85:Х=17
2. В*27=459
3. (Х+74)-91=35
4. 54-(Х-19)=38
5. Х-479=164
6. 62-(х-23)=34
7. (х+83)-92+45
8. Х*43=2451

Answer 1

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
