\(\left(-4,6\right)x-1,53-5,4x=8,47\)
\(\Rightarrow\left(-4,6\right)x-5,4x-1,53=8,47\)
\(\Rightarrow x\left[\left(-4,6\right)-5,4\right]=8,47+1,53\)
\(\Rightarrow x.\left(-10\right)=10\)
\(\Rightarrow x=10:\left(-10\right)\)
\(\Rightarrow x=-1\)
Vậy \(x=-1\)
\(-4.6x-1.53-5.4x=8.47\\ \Leftrightarrow\left(-4.6x-5.4x\right)-1.53=8.47\\ \Leftrightarrow-10x=8.47+1.53\\ \Leftrightarrow-10x=10\\ \Leftrightarrow x=-1\)
Vậy \(x=-1\)
\(-1,53:\left(5\dfrac{5}{28}-1\dfrac{8}{9}\cdot1.25+1\dfrac{16}{63}\right)\)
\(=-\dfrac{153}{100}:\left(\dfrac{145}{28}-\dfrac{17}{9}\cdot\dfrac{5}{4}+\dfrac{79}{63}\right)\)
\(=-\dfrac{153}{100}:\left(\dfrac{145}{28}-\dfrac{85}{36}+\dfrac{79}{63}\right)\)
\(=-\dfrac{153}{100}:\dfrac{1395-595+316}{252}\)
\(=-\dfrac{153}{100}\cdot\dfrac{252}{1116}=\dfrac{-153}{100}\cdot\dfrac{7}{31}=\dfrac{-1071}{3100}\)
\(-1,53:\left(5\dfrac{5}{28}-1\dfrac{8}{9}.1,25+1\dfrac{16}{63}\right)\)
\(=-1,53:\left(5\dfrac{5}{28}-\dfrac{17}{9}.\dfrac{5}{4}+1\dfrac{16}{63}\right)\)
\(=-1,53:\left(5\dfrac{5}{28}-\dfrac{17.5}{9.4}+1\dfrac{16}{63}\right)\)
\(=-1,53:\left(5\dfrac{5}{28}-\dfrac{85}{36}+1\dfrac{16}{63}\right)\)
\(=-1,53:\left(\dfrac{145}{28}-\dfrac{85}{36}+\dfrac{79}{63}\right)\)
\(=-1,53:\left(\dfrac{1305}{252}-\dfrac{595}{252}+\dfrac{316}{252}\right)\)
\(=-1,53:\dfrac{1305-595+316}{252}\)
\(=-1,53:\dfrac{1026}{252}\)
\(=\dfrac{-153}{100}:\dfrac{57}{14}\)
\(=\dfrac{-153}{100}.\dfrac{14}{57}\)
\(=\dfrac{-153.14}{100.57}\)
\(=\dfrac{-2142}{5700}\)
\(=\dfrac{-357}{950}\)
\(\frac{5}{42}-x=\frac{551}{364}\)
\(\Rightarrow x=\frac{5}{42}-\frac{551}{364}\)
\(\Rightarrow x=-\frac{1523}{1092}\)
Vậy : \(x=-\frac{1523}{1092}\)
