a) \frac{2}{x} =\frac{3}{x-1}
b) \frac{4}{x+1} = \frac{5}{x}
c) \frac{0,4x-1}{3} = \frac{2x-5}{2}
d) \frac{2x-1}{1-2x} = \frac{2}{3}
e) \frac{3}{5} = \frac{2x-1}{2-3x}
f) \frac{4-x}{3} = \frac{x-1}{1-3x}

2. Rozwiąż równania
a) 4(a-1)=6(1+a)
b) 8x-(1+2x)=2(3x-0,5)
c) x-2(x-1)=0,2(1-2x)
d) 2(5x-4)-5(x-3)=x-2(4-2x)
e) x-5[2x-3(x+6)]=-4(x-5)
f) 3(x-4)-2x(x+2)=(1-2x)

3.Rozwiąż równania:

a) 1\frac{3}{4} = 2(x+2)+3(x+\frac{1}{4})
b) \frac{4x+7}{2} - \frac{5x-1}{6} = x+5
c) \frac{5(x-1)}{3}- \frac{3(2x-3)}{2}=2\frac{1}{2} -x
d) \frac{x+5}{4}- \frac{2x+1}{8} = \frac{1}{2}(2-x)
e) \frac{1}{2}x - \frac{3}{4}[x-(4x+1)]=1-\frac{x+1}{4}
f) \frac{2}{3}(3x-1)-\frac{3}{2}[2x+3(x-2)]=1
g) \frac{0,4x-2}{5} - \frac{0,12x-1,4}{8} = 0,03(2-x)
