20道分式方程及答案,只是计算 20道分式方程及答案,是计算的.

Answer 1

1/2x=2/x +3
x/(x+1)=2x/(3x+3)+1
2/x -1=4/x^2 -1
5/x^2+x - 1/x^2 -x=0
5x/(3x-4)=1/(4-3x)-2
7/(x^2+x)+1/(x^2-x)=6/(x^2-1)
1/(x-2)=(1-x)/(2-x) -3
3/(x+1)-2/(x+2)=x/(x^2+3x+2)
x/(2x-3)+5/(3-2x)=4
1/(1-x^2)=3/(1-x)-5/(1+x)
4/(x-2)-16/(x^2-4)=-3/(x+2)
80/(x+3)=60/(x-3)
1/(x-1)=2/(x^2-1)
100/x=30/(x-7)
2640/2x=2640/x -120
2/x=3/(x+1)
2x/(2x+5)+5/(5x-2)=1
x/(x-6)=(x-2)/(x-3)
(x-1)/(x-2)=1/(x-2)
1/(x^2+5x-6)=1/(x^2+x+6)
