\(\Leftrightarrow\dfrac{x+350}{x}+315=341\)
\(\Leftrightarrow1+\dfrac{350}{x}=26\)
=>350/x=25
hay x=14
b) .
368 - 27 = \(\dfrac{x+350}{x}+315\)
=> \(\dfrac{x+350}{x}+315=341\)
=> \(\dfrac{x+350}{x}=26\)
=> \(x+350=26x\)
=> \(x+350-26x=0\)
=> \(350-25x=0\) = > 25x = 350 => x = 350 / 25 = 14
\(92\cdot4-27=\left(x+350\right):x+315\\ \Leftrightarrow368-27=\left(x+360\right):x+215\\ \Leftrightarrow341=\left(x+360\right):x+215\\ \Leftrightarrow\left(x+360\right):x=341-215\\ \Leftrightarrow\left(x+360\right):x=126\\ \Leftrightarrow\left(x:x\right)+\left(360:x\right)=126\\ \Leftrightarrow1+360:x=126\\ \Leftrightarrow360:x=125\\ \Leftrightarrow x=2,88\)
