1. \( \frac{15}{8} - \frac{1}{8} \left( x - 0.5 \right) = \frac{5}{4} \)
2. \( \frac{3}{4} + \frac{1}{5} \cdot x = \frac{1}{4} \)
3. \( -2x - \frac{2}{3} \left( \frac{3}{4} - \frac{1}{8} \cdot x \right) = \left( -\frac{1}{2} \right)^3 \)
4. \( (3x + 2)(5 - x^2) = 0 \)
5. \( |x - 1| \cdot \left| \frac{2}{3} - \frac{3}{4} \right| = 2 \)
6. \( |x - \frac{2}{3}| = \frac{2}{5} = \frac{1}{3} \)
