\(-\frac{5}{6}x-1\frac{13}{19}:3\frac{7}{19}-\left(-0,12\right)=\left(-\frac{1}{2}\right)^2\)
\(\Rightarrow-\frac{5}{6}x-\frac{32}{19}:\frac{64}{19}+0,12=\frac{1}{4}\)
\(\Rightarrow-\frac{5}{6}x-\frac{1}{2}=\frac{1}{4}-0,12=\frac{13}{100}\)
\(\Rightarrow-\frac{5}{6}x=\frac{63}{100}\)
\(\Rightarrow x=-\frac{189}{250}\)
-5/6x-32/19:64/19+3/25=1/4
-5/6x-32/19×19/64+3/25=1/4
-5/6x-1/2+3/25=1/4
-5/6x-31/50=1/4
-5/6x=1/4+31/50
-5/6x=87/100
x=87/100:-5/6
x=87/100×-6/5
x=-261/250
vậy x=-261/250
\(\frac{-5}{6}x-1\frac{13}{19}\div3\frac{7}{19}-\left(-0.12\right)=\left(\frac{-1}{2}\right)^2\)
\(\Leftrightarrow\frac{-5}{6}x-\frac{32}{19}\div\frac{64}{19}-\left(\frac{-3}{25}\right)=\frac{1}{4}\)
\(\Leftrightarrow\frac{-5}{6}x-\frac{32}{19}\times\frac{19}{64}+\frac{3}{25}=\frac{1}{4}\)
\(\Leftrightarrow\frac{-5}{6}x-\frac{1}{2}+\frac{3}{25}=\frac{1}{4}\)
\(\Leftrightarrow\frac{-5}{6}x-\frac{19}{50}=\frac{1}{4}\)
\(\Leftrightarrow\frac{-5}{6}x=\frac{63}{100}\)
\(\Leftrightarrow x=\frac{-189}{250}\)
Vậy \(x=\frac{-189}{250}\)
Học tốt nhé
