x - 4867 = ( 175 . 2050 . 70 ) : 25 + 23
x - 4867 = ( 358750 . 70 ) : 25 + 23
x - 4867 = 25112500 + 23
x - 4867 = 1004500 + 23
x- 4867 = 1004523
x = 1004523 + 4867
x = 1009390

\(\frac{x+350}{x}=26\)
\(\left(x+350\right):x=26\)
\(x+350=x.26\)
\(350=x.25\)
\(x=350:25\)
\(x=14.\)
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
a) \(697:\frac{15X+364}{X}=17\)
\(\Rightarrow\frac{15X+364}{X}=697:17=41\)
\(\Rightarrow15X+364=41X\)
\(\Rightarrow364=41X-15X=26X\)
\(\Rightarrow X=14\)
