tìm x

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

Answer 1

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

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

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

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

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

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

\(x+350=x.26\)

\(350=x.25\)

\(x=350:25\)

\(x=14.\)

                                                           Đáp số : 14.

Answer 2

92.4 - 27 = ( x+ 350) / x +315

hay 341 = (x+ 350) / x +315

=> 26 = (x+ 350) / x 

=> 26x = x + 350

=> 25x = 350

=> x= 14
