(1)去分母得:4x-8=3x+9,
解得:x=17,
经检验x=17是分式方程的解;
(2)去分母得:3x=4x-4,
解得:x=4,
经检验x=4是分式方程的解;
(3)去分母得:600-480=8x,
解得:x=15,
经检验x=15是分式方程的解;
(4)去分母得:x-5=2x-5,
解得:x=0,
经检验x=0是分式方程的解;
(5)去分母得:1+3x-6=x-1,
解得:x=4,
经检验x=4是分式方程的解;
(6)去分母得:2x+9=12x-21+6x-18,
解得:x=3,
经检验x=3是分式方程的解;
(7)去分母得:2=3(1-x),
解得:x=
,
经检验是分式方程的解;
(8)去分母得:x+1=(x-2)(x-1)-x
2+1,
解得:x=
,
经检验是分式方程的解;
(9)去分母得:2x(x+2)+2(x-1)=2(x-1)(x+2),
整理得:x=-
,
经检验是分式方程的解;
(10)去分母得:(3-2x)(x-3)-(1-x)(x-3)=(1-x)(x+2),
整理得:3x-9-2x
2+6x-x+3+x
2-3x=x+2-x
2-2x,即6x=11,
解得:x=
,
经检验是分式方程的解;
(11)去分母得:(x-1)
2-x(x+1)=4,
整理得:x=-1,
经检验x=-1是增根,原分式方程无解.
