Question

tìm x

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

Answer 1

368-27=(x+350):x+315

341=(x+350):x+315

x:x+350:x=341-315

1+350:x=26

350:x=26-1

350:x=25

x=350:25

x=14

hk tốt

Answer 2

     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

Answer 3

tít cho mình trước nha

Answer 4

\(92.4-27=\frac{\left(x+350\right)}{x}+315\Leftrightarrow368=\frac{x+350}{x}+315\)

\(\Leftrightarrow\frac{x+350}{x}=53\Leftrightarrow x+350=53x\Leftrightarrow-52x=-350\Leftrightarrow x=\frac{175}{26}\)
