20道分式方程!!
明上学了,老师抽风让写三十五道分式方程,就x+1分之x=3x+3分之2x的这种,比较急,在线等,有答案就行!!!拜托了QAQ...

(10X+7)/(70+X)=3/8 X=2
2/(x+2)+1/(x+1)=3/x x=1或-1
3/5÷x=(1-3/5)÷(x-10) x=30
80/(x+3)=60/(x-3) x=21
(12*10000/X)*(3/2)*(X+5)=18.75*10000 X=120
1/2x=2/x+3 x=1
x/(x+1)=2x/(3x+3)+1 x=-3/2
2/x-1=4/x^2-1 x=1分式方程要检验经检验,x=1使分母为0,是增根,舍去所以原方程无解
5/x^2+x - 1/x^2-x=0 x=3/2
1/(x+2) + 1/(x+7) = 1/(x+3) + 1/(x+6) x=-9/2
2/(x+2)+1/(x+1)=3/x x=1或-1
