BÀI 3: Tìm x. 1) \( \frac{3}{4} x + \frac{1}{5} = 2 \)
2) \( \frac{1}{4} x = \frac{5}{8} \)
3) \( \frac{3}{4} x + \frac{11}{12} \)
4) \( 4 - \frac{2}{3} x - \frac{4}{15} \)
5) \( 2x - \frac{1}{4} = \frac{2}{3} \)
6) \( 6 - 2|1 - \frac{5}{8} - \frac{3}{5}| = 6 \)
7) \( \frac{9}{15} - \frac{1}{3} \)
8) \( \frac{3}{10} \)
