若单项式M.N满足等式3xM-5x)=6x²y³+N则M= N= 若单项式M.N满足等式3xM-5x)=6x²y³+N则M= N= 已知单项式M,N满足等式3x(M-5x)=6xy+N,则M= ,N= 已知单项式M、N满足等式3x[M-5x]=6xxyyy+N,求M、N 已知单项式M,N满足等式3x(M-5x)=6x平方y3次方+n,求MN 已知单项式M,N满足等式3x(M-5x)=6x平方y3次方+n,求MN 若单项式M,N满足等式3x(M-5x)=6x2y3+N,则M-N为_____最好有过程! 若单项式M,N满足等式2x(M-5x)=6x²y³+N,则M-N为 已知单项式M,N满足等式3x(M-5x)=6x平方y3次方+n,则M= ,N=过程!~~~~~~~~~~~ 已知单项式M,N满足等式3x(M-5x)=6x^2y^3+N.求M,N. 已知单项式M、N满足等式3x（M-5x）=6x²y³+N,求M、N 已知单项式M N满足等式3x（m－5x）=6x²y²+N求M N 已知单项式M、n满足等式3x（m-5x）=6X^2Y^3 N,则m= 若两个单项式5xm次方与-1/3x²y的m-n次方的和仍是单项式，则m=n= 已知单项式M,N满足3x(M-5x）=6x²y²+N,求MN.老师说的是：3xM-15x²=6x²y²+N,3xM=6x²y²,-15x²=N,我不知道为什么,好的有加悬赏. 已知单项式M、N满足等式:2x(M-x)=6x^2y^3+Nx^2,求M+N 已知单项式M,N满足3x(M-5x)=6x^2y^3+N,求M,N 已知单项式M、N满足等式：2x(M-x）=6x²y三次方+Nx²,求M、N.上面是求M+N. 已知单项式M,N,满足3x（M-5x）=6xy,+N,则M= ,N=
