Tìm x:
a) 5\(\frac{4}{7}\): x =13
b) \(\frac{4}{7}\)x=\(\frac{9}{8}\)-0,125
c) \(\frac{2}{3}\)x-\(\frac{1}{2}\)=\(\frac{1}{10}\)
d) \(\frac{1}{3}\)x-0,5x = -1\(\frac{1}{4}\)
e) \(\frac{-5}{6}\)- x = \(\frac{7}{12}\)+ \(\frac{-1}{3}\)
f) \(\frac{x+2}{3}\)=\(\frac{x-2}{2}\)
g) \(\frac{2}{5}\)- \(\frac{1}{5}\): x = -25%
h) (2\(\frac{4}{5}\)x - 50): \(\frac{2}{3}\)= 51
i) \(\frac{2}{3}\)x -\(\frac{1}{2}\)x =\(\frac{5}{12}\)
j) \(\frac{7}{2}\)- |2x -\(\frac{3}{4}\)| = -\(\frac{7}{4}\)
k) (x : 6\(\frac{2}{7}\)+\(\frac{3}{7}\)) :2\(\frac{1}{5}\)-\(\frac{3}{7}\)= -2
l) (x +\(\frac{1}{5}\))2 +\(\frac{17}{25}\)=\(\frac{26}{25}\)
m) (x +\(\frac{1}{2}\))(\(\frac{2}{3}\)- 2x) =0
Mọi người ơi giúp mình nhanh nha.
Ai giúp mình thì mình sẽ tick cho.
