Question

Решите уровнения !!!!!!!!! 30*(x*6)=189720, 3438+x/6=10004. (800-180)/x=20

Answer 1

180х=189720
х=189720:180
х=10054

х/6=10004-3438
х/6=6566
х=6566*6
х=39396

620/х=20
х=620:20
х=31

Answer 2

1) 30*(х*6) = 189720
х*6 = 189720 : 30
х*6 = 6324
х = 6324 : 6
х = 1054
2) 3438 + х : 6 = 10004
х : 6 = 10004 - 3438
х : 6 = 6566
х = 6566*6
х = 39396
3) (800 - 180) : х = 20
620 : х = 20
х = 620 : 20
х = 31
