Question

как решить уровнение 14*X=42 811-X=517 64*X=8 X+175=304

Answer 1

14*Х=42

Х=42:14

Х=3                 

 

811-X=517

Х=811-517

Х=294

 

 

64*X=8

Х=64:8

Х=8

 

 

X+175=304

Х=304-175

Х=129

Answer 2

1) 14*х=42

х= 42:14

х=3

2) 811-х=517

х=811-517

х= 294

3)64*х=8                              или                     3) 64:х=8

х=8:64                                                                   х=64:8

х=0,125                                                                 х=8

4) х+175=304

х=304-175

х=129
