`x/8=-1/4`
`(x:2)/4=-1/4`
`x:2=-1`
`x=-1 xx2`
`x=-2`
\(\dfrac{x}{8}=\dfrac{-1}{4}\)
=>x.4=-1.8
=>x.4=-8
=>x=-8:4=-2
Vaayj x=-2
a) C1: \(\dfrac{x}{8}=\dfrac{-1}{4}\)
\(\dfrac{x:2}{8:2}=\dfrac{-1}{4}\)
\(\dfrac{x:2}{4}=\dfrac{-1}{4}\)
\(\Rightarrow\) \(x:2=-1\)
\(x=-1.2\)
\(x=-2\)
C2: \(\dfrac{x}{8}=\dfrac{-1}{4}\)
\(\Rightarrow x.4=8.\left(-1\right)\)
\(x.4=-8\)
\(x=-8:4\)
\(x=-2\)
\(\dfrac{x}{8}\)=\(\dfrac{-1}{4}\)
x=8.-1:4
x=-2
\(\dfrac{-2}{8}\)=\(\dfrac{-1}{4}\)
Giải:
\(\dfrac{x}{8}=\dfrac{-1}{4}\)
\(\Rightarrow x=\dfrac{8.-1}{4}=-2\)
Chúc bạn học tốt!
\(\dfrac{x}{8}=-\dfrac{1}{4}\)
\(\dfrac{x:2}{4}=-\dfrac{1}{4}\)
\(x:2=-1\)
\(x=-1.2\)
\(x=-2\)
