\(\frac{15.a+364}{a}\)= 697:17=41

15+\(\frac{364}{a}\)=41

\(\frac{364}{a}\)=41-15=26

       a=364:26

        a=14

368-27=\(\frac{a+350}{a}\)+315

314=\(\frac{a+350}{a}\)+315

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

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

a+350=26.a

26.a-a=350

(26-1).a=350

25.a=350

     a=350:25

     a=14

KUDO SHINICHI:

        Bài làm:

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

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

\(341=\frac{x}{350+315}\Leftrightarrow341=x:350+315\)

\(341=x:665\)

\(x=665.341\)

\(\rightarrow x=226765\)

Vậy x=226765

:3, Chúc bạn học tốt!!

92.4-27=x+350/x +315

368 - 27 = x+350 : x + 315

341 = x : (350 + 315)

341 = x : 665

x = 665 x 341

x = 226765

cam on cac ban

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.

khong can lam nua dau minh biet lam roi

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

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

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

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

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

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

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

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

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

\(\Leftrightarrow350:x=25\)

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

Vậy x=14
