| x : ( -5/6 ) – 3/4 | = 2 ( giải cụ thể từng bước ) 01/10/2021 Bởi Mary | x : ( -5/6 ) – 3/4 | = 2 ( giải cụ thể từng bước )
\(\left| {x : \dfrac{-5}{6} -\dfrac{ 3}{4}}\right | = 2\) TH1: \(x : \dfrac{-5}{6} -\dfrac{ 3}{4} = 2\) \(\Rightarrow x : \dfrac{-5}{6} =2+\dfrac{3}{4}\) \(\Rightarrow x : \dfrac{-5}{6} =\dfrac{11}{4}\) \(\Rightarrow x=\dfrac{11}{4}.\dfrac{-5}{6}\) \(\Rightarrow x=\dfrac{-55}{24}\) ™ TH2: \(x : \dfrac{-5}{6} -\dfrac{ 3}{4} = -2\) \(\Rightarrow x : \dfrac{-5}{6} =-2+\dfrac{3}{4}\) \(\Rightarrow x : \dfrac{-5}{6} =\dfrac{-5}{4}\) \(\Rightarrow x=\dfrac{-5}{4}.\dfrac{-5}{6}\) \(\Rightarrow x=\dfrac{25}{24}\) ™.

TH1: x: ( -5/6) – 3/4= 2 x:(-5/6) = 2+ 3/4 x:(-5/6) =11/4 x = 11/4.(-5/6) x = -55/24 TH2: x: ( -5/6) – 3/4= – 2 x:(-5/6) = -2+ 3/4 x:(-5/6) =-5/4 x = -5/4.(-5/6) x = 25/24 Vậy x=-55/24 hoặc x=25/24 Bình luận
\(\left| {x : \dfrac{-5}{6} -\dfrac{ 3}{4}}\right | = 2\)
TH1: \(x : \dfrac{-5}{6} -\dfrac{ 3}{4} = 2\)
\(\Rightarrow x : \dfrac{-5}{6} =2+\dfrac{3}{4}\)
\(\Rightarrow x : \dfrac{-5}{6} =\dfrac{11}{4}\)
\(\Rightarrow x=\dfrac{11}{4}.\dfrac{-5}{6}\)
\(\Rightarrow x=\dfrac{-55}{24}\) ™
TH2: \(x : \dfrac{-5}{6} -\dfrac{ 3}{4} = -2\)
\(\Rightarrow x : \dfrac{-5}{6} =-2+\dfrac{3}{4}\)
\(\Rightarrow x : \dfrac{-5}{6} =\dfrac{-5}{4}\)
\(\Rightarrow x=\dfrac{-5}{4}.\dfrac{-5}{6}\)
\(\Rightarrow x=\dfrac{25}{24}\) ™.
TH1: x: ( -5/6) – 3/4= 2
x:(-5/6) = 2+ 3/4
x:(-5/6) =11/4
x = 11/4.(-5/6)
x = -55/24
TH2: x: ( -5/6) – 3/4= – 2
x:(-5/6) = -2+ 3/4
x:(-5/6) =-5/4
x = -5/4.(-5/6)
x = 25/24
Vậy x=-55/24 hoặc x=25/24
