\(\dfrac{-2}{3}:x+\dfrac{5}{8}=\dfrac{-7}{12}\)
\(\dfrac{-2}{3}:x=\dfrac{-7}{12}-\dfrac{5}{8}\)
\(\dfrac{-2}{3}:x=\dfrac{-29}{24}\)
\(x=\dfrac{-2}{3}:\dfrac{-29}{24}\)
\(x=\dfrac{16}{29}\)
\(-\dfrac{2}{3}:x+\dfrac{5}{8}=-\dfrac{7}{12}\)
\(-\dfrac{2}{3}:x=-\dfrac{29}{24}\)
\(x=\dfrac{16}{29}\)
=.= hk tốt!!
