3m-2n=7 3m-n=5
3m-2n=7 3m-n=5
3m-2n=7 3m-n=5
3m-2n=7 (1)
3m-n=5 (2)
(2)-(1)
n=-2 带入 (2)
m=1
n=2 M=2/3
.4(m+n)^2*(m+n)^3-7(m+n)(m+n)^4+5(m+n)^5=
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=7/3则m+n/m-n
(m-n)^3(n-m)^2(m-n)=_____
3m+2n=7 3m-n=5m=?n=?
(3m-n)(m-2n)=()
m-[n-3m-(m-n)]=?
m-{n-2m+[3m-(6m+3n)+5n]}=
已知m=5 4/7,n=4 3/7, 求代数式[-7/2(m+n)]^3×(m-n)×[-2(m+n)(m-n)]^2的值
已知3m=2n,则m/(m+n)+n/(m-n)-n^2/(m^2-n^2)=?
7m+2n/5(m+n) :4m+13n/3(m+n)=183:385怎么做到结果得m:n=3:
求解4(m+n)^2*(m+n)^3-7(m=n)(m+n)^4+5(m+n)^5
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
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
如果m和n互为相反数,则m+2m+3m+4m+5m+5n+4n+3n+2n+n=
