3) Tính:
1) \( \frac{1}{3} + \frac{3}{2} + \frac{3}{5} \)
2) \( \left( \sqrt{2} - \sqrt{5} \right) \cdot \left( 3 - \left| -x - 2 \right| \right) - \frac{1}{3} = 3 \)
3) \( 3x^2 + 4x + 1 + \frac{2}{3}x + 2 = 6 \)
4) \( \frac{4}{5} + 1 - x - \left| -3.2 - \frac{2}{5} \right| \)
5) \( 6 - 2\sqrt{3}x + 7 \)
