2.①(x+2)/3+(y-1)/2=2②(x+2)/3+(1-y)/2=1
①m/3-n/4=3② m/2-n/3=132.①(x+2)/3+(y-1)/2=2②(x+2)/3+(1-y)/2=1
解由m/3-n/4=3
得4m-3n=36.1
由m/2-n/3=13
得3m-2n=78.2
1式×2-2式×3
即m=162,n=204
请采纳答案,支持我一下.
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=
(3m-n)(m-2n)=()
m-[n-3m-(m-n)]=?
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))
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=?
解二元一次方程组!(m+n)/3 - (m-n)/4=0.35 ① (m+n)/3 + (m-n)/2=0.5 ②
|m-n|=n-m,且|m|=4,|n|=3,求(m+n)*(m+n)的值
(m+4)^2+|n+3|=01/2m-n
4m(m-n)^2+4n(n-m)^3
