\(\dfrac{3}{3}\) - ( \(\dfrac{3}{5}\) + x ) = \(\dfrac{2}{7}\)
\(\dfrac{5}{12}\)-(-\(\dfrac{3}{8}\)-x)=\(-\dfrac{5}{6}\)
\(\dfrac{2}{3}\)-\(\left(-\dfrac{7}{4}-\left(\dfrac{1}{2}+\dfrac{3}{8}\right)\right)\)
(\(-\dfrac{25}{27}\)-\(\dfrac{31}{42}\)) - (\(-\dfrac{7}{27}\)-\(\dfrac{3}{42}\))
cứu vs
\(-\dfrac{1}{6}\)x\(-\dfrac{15}{19}\)x\(\dfrac{38}{45}\)
