Bài 4: Tìm x biết:
1) \( \frac{5}{8} + \frac{1}{4} (2x-1) = \frac{5}{4} \)
2) \( \frac{8}{7} - \frac{1}{7} \left( \frac{x}{3} - 2 \right) = -1 \)
3) \( 5 \cdot \frac{1}{2} - \frac{1}{2} (2x + 1) = \frac{1}{2} \)
Bài 5: Tìm x biết:
1) \( \left( x + \frac{1}{2} \right) \left( \frac{2}{3} - 2x \right) = 0 \)
2) \( (4x + 1) \left( -2x + \frac{1}{3} \right) = 0 \)
3) \( (5x - 1) \left( 2x - \frac{1}{3} \right) = 0 \)
