若3m-2n-2=0,则4n-6m-3等于多少?

已知3m=4n,则m/m+n+n/m-n-m^2/m^2-n^2= 1若m=n,则|m|=|n|;2若m=—n,则|m|=|n|;3若|m|=|n|,则m=—n;4若|m|=|n|,则m=n哪个对 若(m-2n)/(2m+n)=3,则[3(m-2n)/(2m+n)-(m-2n)/[2(2m+n)] - {9(m-2n)/[4(2m+n)]}的值是? 若有理数m,n满足m-2n=4,2m-n=3,则m+n等于 若|m-n|=n-m,且|m|=4、|n|=3,则（m+n)^2= 若|m-n|=n-m,且|m|=4,|n|=3,则(m+n)^2=? 若m^2+n^2-6n+4m+13=0则m-n=? 若m+n=0,则多项式m^3-m^3n-mn^2+n^3 若m^2-n^2=6,且m-n=3,则m+n=? 若|m-n|+(m+2n-3)²=0,则m+n的值是 若m、n互为相反数,则(5m-3n)-(2m-6n)= 已知3m=2n,则m/(m+n)+n/(m-n)-n^2/(m^2-n^2)=? 根号m+2n+6+根号2m+m-3=0,则m+n= 如果m和n互为相反数,则m+2m+3m+4m+5m+5n+4n+3n+2n+n= 若m-n=3,3m+2n=2,求代数式6m（m-n）-4n（n-m）的值 (m-2n)(2n+m)-(-3m-4n)(4n-3m)= 若3m-2n-2=0,则4n-6m-3= 若3m-2n-2=0,则4n-6m-3等于多少?
