\(92.4-27=\left(x+350\right):x+315\)

\(\Leftrightarrow368-27=\left(x+350\right):x+315\)

\(\Leftrightarrow341=\left(x+350\right):x+315\)

\(\Leftrightarrow\left(x+350\right):x=341-315\)

\(\Leftrightarrow\left(x+350\right):x=26\)

\(\Leftrightarrow\left(x:x\right)+\left(350:x\right)=26\)

\(\Leftrightarrow1+350:x=26\)

\(\Leftrightarrow350:x=26-1\)

\(\Leftrightarrow350:x=25\)

\(\Leftrightarrow x=\dfrac{350}{25}=14\)

Vậy x=14

92.4-27=(x+350) : x + 315

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

341=1+350 : x +315

341-315-1=350 : x

25=350 : x

350 : 25=x

14=x

vậy x=14

Đáp án là \(\frac{-250}{179}\)nha bạn.

x =14 nha bạn

k tui nha

thanks

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

\(< =>368-27=\frac{x+350}{x}+315\)

\(< =>341=\frac{x+350}{x}+315\)

\(\frac{x+350}{x}=341-315\)

\(\frac{x+350}{x}=26\)

\(\left(x+350\right):x=26\)

\(x+350=x.26\)

\(350=x.25\)

\(x=350:25\)

\(x=14.\)

                                                           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

điều kiện x khác 0

suy ra: 341= (x+350)/x +315

26= (x+350)/x

26x = x +350

suy ra x=14

\(92.4-27=\dfrac{x+350}{x}+315\)

\(\Rightarrow366=1+\dfrac{350}{x}+315\)

\(\Rightarrow366=316+\dfrac{350}{x}\)

\(\Rightarrow50=350:x\)

\(\Rightarrow x=7\)

(x+350):x+315=92.4-27

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

(x+350):x+315=341

x+350:x=341-315

x+350:x=26 

x+350=26.x

350-26=x²

324=x²

Suy ra x=18

Lời giải là

92.4−27=a+350a+315

368−27=a+350a+315

341=a+350a+315

a+350a=341−315

a+350a=26

a+350=26.a

26.a−a=350

(26−1).a=350

25.a=350

a=350:25

a=14.

a)720:[41-(2x+5)]=2³.5

720:[41-(2x+5)]=8.5

720:[41-(2x+5)]=40

41-(2x+5)=720:40

41-(2x+5)=18

2x=18-5

2x=13

x=13:2

x=6,5

b)92.4-27=(x+350):x+315

=>(x+350):x+315=92.4-27

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

(x+350):x+315=341

 tới đấy mk ko biết làm nữa
