Tìm x :
a) \(\frac{-1}{4}\). (\(\frac{x}{4}\)+ \(\frac{-2}{7}\)+ \(\frac{2}{8}\)) = \(\frac{-1}{7}\)+ \(\frac{2}{14}\)
b) \(\frac{5-x}{12}\)+ \(\frac{5}{12}\)- \(\frac{1}{8}\)= \(\frac{3}{8}\)
c) \(\frac{-12}{25}\). (\(\frac{3}{4}\)- x + \(\frac{6}{11}\)) = 0.
Ai nhanh mình tick , mình rất gấp lắm rồi.
