Bài 3 : giải các phương trình sau < phương trình chứa ẩn ở mẫu )
a, 2x/x+1 + 3(x-1)/x=5
b, 1-x/x+1 + 3 = 2x+3/x+1
c, (x+2)^2/2x-3 -1 = x^2+10/2x-3
d, x-1/x-2 - 3 + x= 1/x-2
e, x-2/1-x= 1/x-1 -1-2x
f, 2/x-2 -1/x=2/x^2-2x
g, x-1/x+2 - x/x+2=5x-8/x^2-4
h,3x+2/3x-2-6/2+3x=9x^29x^2-4
k,x/2x-6 +x/2x +2-2x/(x+1)(x-3)=0
l,x+3/x+1 +x-5/x=2
m,4+3x/3 = x^2+1/x
n,1/x+1 -5/x-2 = 15/(x+1)(2-x)
o, 1/2x-3 - 3/x(2x-3) = 5/x
p, 6/x-1 - 4/x-3 = 8/2x-6
q, 3/(x-1)(x-2) + 2/(x-3)(x-1) = 1/(x-2)(x-3)
r,1/x-2 = 5/x+1 =3/2-x
s, 5x/2x + 1 = -6/x+1
t,x+1/x-1 - x-1/x+1 = 4/x^2-1
u, 3x/x-2 - x/x-5 = 3x/ (x-2)(5-x)
