m-n=2, m-2n+3=3求m,n?
m-n=2, m-2n+3=3求m,n?
m-n=2, m-2n+3=3求m,n?
n=2,m=4
m/n=5/3,求(m/m+n)+(m/m+n)-(n^2/m^2-n^2)
已知m/n=5、,求(m/(m+n))+(m/(m-n))-(n^2/(m^3-n^2))
(m-n)^3(n-m)^2(m-n)=_____
(3m-n)(m-2n)=()
若2m=3n,求分式(1+m/n-n/n-m)除以(1-m/n-n/n+m)的值
若2m=3n,求分式(1+m/n-n/n-m)除以(1-m/n-n/n+m)的值
已知|2m-n/m+2n|=3,求2(2m-n)/m+2n-2m-n/m+2n-3的值
已知|2m -n/m+2n|=3求2(2m-n)/m+2n-2m-n/m+2n-3的值
若2m-n/m+2n=5,求3(2m-n)/m+2n-m+2n/2m-n+3的值
若2m-n/m+2n=5,求3(2m-n)/m+2n-m+2n/2m-n+3的值
诺2m-n/m+2n=5,求3(2m-n)/m+2n-m+2n/2m-n+3的值
已知m-2n/2m+n=5,求代数式3(m-2n)/2m+n-15(2m+n)/m-2n-2
如果m,n互为相反数,求m+2m+3m+4m+5m+5n+4n+3n+2n+n=多少
当m-n/m+n=3时,求代数式(3m+3n/m-n)-(m-n/m+n)^2的值为多少?
已知3m=2n,则m/(m+n)+n/(m-n)-n^2/(m^2-n^2)=?
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
m^2=n+2,n^2=m+2(m不等于n),求m^3-2mn+n^3的值因为m^2=n+2,n^2=m+2 所以 m^2-n^2=n-m 即 (m-n)(m+n)=n-m m+n=1为什么得m+n=1,求详解.
2m+3n+2m+3n+m+2m+3n+n=______
