     92 . 4 - 27 = (x+ 350 ) : x + 315

<=> 365 -  27 = (x + 350):x +315

<=> 341         = (x+350 : x +315

<=> (x + 350 ): x = 341 - 315

<=> (x + 350 ) : x = 26 

<=>(x + 350 ) . 1/x=26

<=> x . 1/x + 350 . 1/x = 26

<=> 1 + 350/x =26

<=> 350/x       = 26-1

<=> 350 : x      = 25

<=> x               = 350 : 25 

<=> x                = 14

   vậy x = 14

                                                           Đáp số : 14.

92.4 - 27 = ( x+ 350) / x +315

hay 341 = (x+ 350) / x +315

=> 26 = (x+ 350) / x 

=> 26x = x + 350

=> 25x = 350

=> x= 14
