Bài 3: Tìm x biết
a) \(\frac{1}{6} - \frac{3}{8} = \frac{-6}{21}\)
b) \(x \cdot \frac{3}{4} - \frac{2}{3} = \frac{3}{4} \cdot 4 - x = -3\)
c) \((-0,6x - \frac{1}{2}) = \frac{3}{4} - (-1) = \frac{1}{3}\)
d) \(\frac{2}{9} + \frac{8}{3} = -\frac{2}{3}\)
e) \(x \cdot \frac{3}{4} - \frac{1}{4} = \frac{1}{3} \cdot 4 - x = -5\)
f) \(1 - \frac{1}{3} (2x - 1) = -5\)
g) \(\frac{1}{4} + \frac{1}{3} (2x - 1) = -5\)
h) \((2x + \frac{3}{5}) - \frac{9}{25} = 0\)
i) \(3 (3x - \frac{1}{2}) + \frac{1}{9} = 0\)
j) \(4^2 - \frac{3 \cdot 4}{9} + 1\)
k) \(-\frac{2}{3} - \frac{1}{3} (2x - 5) = -\frac{3}{2}\)
l) \(\frac{x}{2} + \frac{11}{5} + \frac{7}{8} \cdot \frac{64}{49}\)
m)
