李志蜀回答:
45/(x-5)=2*45/(x-5+10)100000/(x+1000)=80000/x3/x=2/(x-6)
5/x=64/x+1882/a=74/x+998/x=490/(x+3)
100/(20+x)=200/(50+x)45/x=410/(x+8)948-45/x=97/3x
1/2x=2/(x+3)x/(x+1)=2x/(3x+3)+12/(x-1)=4/(x^2-1)
5/(x^2+x)-1/(x^2-x)=0(x-3)/(x+4)=(x+9)/(x-7)x/(x-1)=3/(2x-2)-2
2/(2x-1)=4/(4x^2-1)x/(x-4)=(x+1)/(x-1)(2x+1)/(x^2+x)=5/(6x+6)
3/2-1/(3x-1)=5/(6x-2)3/(x-7)=2/(x-6)2/(x+1)-3/(x-1)=6/(x^2-1)
(x+1)/(x-1)-4/(x^2-1)=12x/(2x-1)+x/(x-2)=22/(5+x)-1/(1+x)=5
6/(3x-8)=(4x-7)/(8-3x)+91/(x+1)-5/(2x+2)=7(2x+9)/(x+3)-1/(x-3)-2/x=2
2/(x^2+x)+3/(x^2-x)-4/(x^2-1)=0(5x+2)/(x^2+x)=3/(x+1)2x/(2x-5)-2/(2x+5)=1
