1. Rozwiąż równania

a) \frac{x}{3} + 1 = \frac{5}{6} + \frac{x}{2}

b) \frac{2x - 3}{4} = \frac{1}{2} + x

c) \frac{x + 2}{9} + \frac{x - 1}{3} = 1

d) \frac{2x + 3}{5} = \frac{2 - x}{3} + x

e) \frac{3x - 5}{2} - \frac{5x - 1}{10} = 0

f) \frac{x}{2} = \frac{2}{5} (4 - x) - 4

g) \frac{2x - 1}{5} - \frac{x - 2}{2} = 0,7x

h) 2x - \frac{3x + 5}{4} = - \frac{1}{4}x - 1

2. Rozwiąż równania

 a) \frac{1}{2} x - \frac{3}{4} [x - (4x + 1)] = 1 - \frac{x + 1}{4}

 b) \frac{2}{3}(3x - 1) - \frac{3}{2} [2x + 3(x - 2)] = 1
