`(5+8/17):x+(-4/17):x+(3+1/7):(17+1/3)=4/11`
`(5+8/17)xx1/x-4/17xx1/x+22/7:52/17=4/11`
`(5+4/17)xx1/x+187/182=4/11`
`89/17xx1/x=-1329/2002`
`x=-118281/34034`
Số to quá ;-;
\(\left(5+\dfrac{8}{17}\right):x+\left(\dfrac{-4}{17}\right):x+\left(3+\dfrac{1}{17}\right):\left(17+\dfrac{1}{3}\right)=\dfrac{4}{11}\)
\(\left(\dfrac{93}{17}+\dfrac{-4}{17}\right):x+\dfrac{52}{17}:\dfrac{52}{3}=\dfrac{4}{11}\)
\(\dfrac{89}{17}:x+\dfrac{3}{17}=\dfrac{4}{11}\)
\(\dfrac{89}{17}:x=\dfrac{4}{11}-\dfrac{3}{17}\)
\(\dfrac{89}{17}:x=\dfrac{35}{187}\)
\(x=\dfrac{89}{17}:\dfrac{35}{187}\)
\(x=\dfrac{979}{35}\)
Mk thấy đề bài thế này mới đúng nếu sai thì nhắc mk nha!
Bài 1:
a: \(x=\dfrac{2}{3}:\dfrac{3}{5}=\dfrac{2}{3}\cdot\dfrac{5}{3}=\dfrac{10}{9}\)
b: \(x=\dfrac{17}{8}:\dfrac{7}{17}=\dfrac{17}{8}\cdot\dfrac{17}{7}=\dfrac{289}{56}\)
c: \(x=-\dfrac{3}{4}:\dfrac{7}{12}=\dfrac{-3}{4}\cdot\dfrac{12}{7}=\dfrac{-63}{28}=-\dfrac{9}{4}\)
d: \(\Leftrightarrow x\cdot\dfrac{1}{6}=\dfrac{3}{8}-\dfrac{1}{4}=\dfrac{1}{4}\)
hay \(x=\dfrac{1}{4}:\dfrac{1}{6}=\dfrac{3}{2}\)
e: \(\Leftrightarrow\dfrac{1}{2}:x=-4-\dfrac{1}{3}=-\dfrac{17}{3}\)
hay \(x=-\dfrac{1}{2}:\dfrac{17}{3}=\dfrac{-3}{34}\)
Ghi đề rõ tí
