413 Решите уравнение:

а) x/(x - 4) - x/(x - 2) = 4/((x - 4)(x - 2));

б) (x + 2)/(x - 5) - 3x/((x - 2)(x - 5)) = 2/(x - 2);

в) (x - 1)(x - 3) = x/(x - 1) + 4/((x - 1)(x - 3));

г) 2/(x - 1) + 5/(x + 2) = 13/(x^2 + x - 2);

д) 2/(x - 1) + 5/(x + 2) = 6/(x^2 + x - 2);

е) 2x/(x + 1) + 6/(x^2 - 3x - 4) = (x - 1)/(x - 4).
