a) \(697:\frac{15X+364}{X}=17\)
\(\Rightarrow\frac{15X+364}{X}=697:17=41\)
\(\Rightarrow15X+364=41X\)
\(\Rightarrow364=41X-15X=26X\)
\(\Rightarrow X=14\)
\(92.4-27=\frac{x+350}{x}+315\)
\(< =>368-27=\frac{x+350}{x}+315\)
\(< =>341=\frac{x+350}{x}+315\)
\(\frac{x+350}{x}=341-315\)
\(\frac{x+350}{x}=26\)
\(\left(x+350\right):x=26\)
\(x+350=x.26\)
\(350=x.25\)
\(x=350:25\)
\(x=14.\)
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

\(697:\frac{15x+364}{x}=17\)
\(\frac{15x+364}{x}=697:17=41\)
\(\frac{15x}{x}+\frac{364}{x}=41\)
\(15+\frac{364}{x}=41\)
\(\frac{364}{x}=41-15=26\)
\(x=364:26=14\)
\(92.4-27=\frac{x+350}{x}+315\)
\(\frac{x+350}{x}+315=341\)
\(\frac{x+350}{x}=341-315=26\)
\(\frac{x}{x}+\frac{350}{x}=26\)
\(1+\frac{350}{x}=26\)
\(\frac{350}{x}=26-1=25\)
\(x=350:25=14\)
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
\(92.4-27=\frac{x+350}{x}+35\)
\(\Leftrightarrow341=\frac{x+350}{x}+35\)
\(\Leftrightarrow1+\frac{350}{x}=306\)
\(\Leftrightarrow \frac{350}{x}=305\)
\(\Leftrightarrow x=\frac{70}{61}\)
\(92.4-27=\frac{x+350}{x}+35\)
\(368-27=\frac{x+350}{x}+35\)
\(\frac{x+350}{x}=368-27-35\)
\(\frac{x+350}{x}=306\)
\(x+350=306x\)
\(306-x=350\)
\(305x=350\)
\(x=\frac{70}{61}\)
