Bài 15. Tìm x biết:
a) \(\frac{7}{2} \left[ \frac{3}{2} \left( x + \frac{7}{2} \right) \right] = -\frac{9}{11}\)
b) \(\frac{9}{2} \left[ \frac{2}{3} \left( x + \frac{7}{4} \right) \right] = -\frac{5}{4}\)
c) \(x = \left[ \frac{17}{2} - \left( -\frac{3}{7} + \frac{5}{3} \right) \right] = -\frac{1}{3}\)
d) \(x - \left[ -\frac{5}{3} \left( \frac{7}{2} + \frac{4}{5} \right) \right] = -\frac{1}{5}\)
