m/x-n/(x+1)=0(m不等于n,mn不等于0)求xm/x-n/(x+1)=0(m不等于n,mn不等于0)求xm/x-n/(x+1)=0(m不等于n,mn不等于0)求x化简得:mx+m-nx=0

m/x - n/(x+1)=0(m不等于n,mn不等于0)求x
m/x - n/(x+1)=0(m不等于n,mn不等于0)求x

m/x - n/(x+1)=0(m不等于n,mn不等于0)求x
化简得:mx+m-nx=0
(m-n)x=-m
x=-m/(m-n)
验证:x(x+1)≠0,∴x≠0且-1
依题意,-m/(m-n)≠0且-1
∴x=-m/(m-n)为原方程的解

x=m/(n-m)
