$frac{1}{5} x - 2 = x - frac{1}{2} \ frac{1}{5}x - x = 2 - frac{1}{2} \ - frac{4}{5}x = frac{3}{2} \ x = frac{3}{2} . (- frac{5}{4} ) = - frac{15}{8} = 1 frac{7}{8}$

$frac{(x-3)}{2} = 3- frac{(x+1)}{4} \ frac{(x-3)}{2} + frac{(x+1)}{4} = 3 \ frac{4(x-3)}{8} + frac{2(x+1)}{8} = 3 \ frac{(4x-12) + (2x+2)}{8} = 3 \ frac{6x-10}{8} = 3 \ 6x - 10 = 24 \ 6x = 34 \ x = 5,6$
