2. Tìm x biết:
1) \( \frac{13}{20} + \frac{3}{5} + x = \frac{5}{6} \)
2) \( x + \frac{1}{3} = \frac{2}{5} \left( -\frac{1}{3} \right) \)
3) \( \frac{2}{3} + x + 1 = \frac{11}{3} \)
4) \( \frac{3}{7} - x = \frac{1}{4} \left( -\frac{3}{5} \right) \)
5) \( -\frac{5}{8} - x = -\frac{3}{20} \left( -\frac{1}{6} \right) \)
