m/3-3=n+3/62n-m/4=3m/3-3=n+3/62n-m/4=3m/3-3=n+3/62n-m/4=3原式化简得:2m-n-21=02n-m-12=0解得:m=18n=15
m/3-3=n+3/6 2n-m/4=3
m/3-3=n+3/6 2n-m/4=3
m/3-3=n+3/6 2n-m/4=3
原式化简得:2m-n-21=0 2n-m-12=0
解得:m=18 n=15
已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2=
(m-2n)(2n+m)-(-3m-4n)(4n-3m)=
(m-n)^3(n-m)^2(m-n)=_____
.4(m+n)^2*(m+n)^3-7(m+n)(m+n)^4+5(m+n)^5=
m-[n-3m-(m-n)]=?
(3m-n)(m-2n)=()
解方程组:{3分之2(m-n)-4分之m+n=-1,6(m+n)-4(2m-n)=16解方程组:{[2(m-n)/3-(m+n)/4=-1,6(m+n)-4(2m-n)=16不是(m+n)/2-(m-n)/3=1 (m+n)/3-(m-n)/4=-1 你看清楚,是:解方程组:{[2(m-n)/3-(m+n)/4=-1,6(m+n)-4(2m-n)=16
已知3m=2n,则m/(m+n)+n/(m-n)-n^2/(m^2-n^2)=?
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-2m+[3m-(6m+3n)+5n]}=
如果m和n互为相反数,则m+2m+3m+4m+5m+5n+4n+3n+2n+n=
如果m,n互为相反数,求m+2m+3m+4m+5m+5n+4n+3n+2n+n=多少
(m-2n)^2+(3m-n)(2m+2n)-(2m+n)(2m-n) 已知m+n=4 mn=1
2m+3n+2m+3n+m+2m+3n+n=______
|m-n|=n-m,且|m|=4,|n|=3,则m+n=?
集合M={m|m=3^n+6n-1,n∈N+,且m
计算(m+4n)(m-n)-6(m+2n)(m-3n)
