c) \( (50\% \cdot x + 2) \frac{1}{4} - \frac{2}{3} = \frac{17}{6} \)

h) \( 1) \left( \frac{2}{3} x - \frac{1}{3} \right) \frac{5}{3} = \frac{2}{4} \)

d) \( 1) \left( \frac{1}{3} - \frac{25\%}{12} \right) - 2x = 1.6 \cdot \frac{3}{5} \)

e) \( (3x + 7) j - 4 = -\frac{1}{28} \)

i) \( \frac{3}{7} - \frac{1}{8} - x = \frac{2}{3} \)

k) \( (4.5 - 2x) \frac{1}{7} = \frac{11}{14} \)
