\(-x-\frac{2}{3}=\frac{-6}{7}\)
\(-x=\frac{-6}{7}+\frac{2}{3}\)
\(-x=\frac{-4}{21}\)
\(\Rightarrow x=\frac{4}{21}\)
Vậy \(x=\frac{4}{21}\)
-x-2/3=-6/7
-x=-6/7+2/3
-x=-4/21
=> x=4/21
\(-x-\frac{2}{3}=-\frac{6}{7}\)
\(-x=-\frac{4}{21}\)
\(x=\frac{4}{21}\)
-x-2/3=-6/7
-x=-6/7+2/3
-x=-4/21
x=4/21
Vậy x=4/21
-x-\(\dfrac{2}{3}\)=\(\dfrac{-6}{7}\)
=>-x=\(\dfrac{-6}{7}+\dfrac{2}{3}\)
=>-x=\(\dfrac{-4}{21}\)
=>x=\(\dfrac{4}{21}\)
Vậy x=\(\dfrac{4}{21}\)
-x - \(\dfrac{2}{3}\)= - \(\dfrac{6}{7}\)
-x = - \(\dfrac{6}{7}\)+ \(\dfrac{2}{3}\)
-x = - \(\dfrac{4}{21}\)
Vậy x = \(\dfrac{4}{21}\)
\(-x-\dfrac{2}{3}=-\dfrac{6}{7}\)
\(-x=-\dfrac{6}{7}+\dfrac{2}{3}\)
\(-x=-\dfrac{4}{21}\)
\(x=\dfrac{4}{21}\)
