This maybe a -x + 2y and maybe a -z... oh, let me make that a -1.

x + 2y - z，哦，让我使它为- 1。

youdao

x*y=3 And lambda x - 2y = 0. And xy = 3.

和λx-2y=0和。

youdao

And, to go from one to the other, x+2y+4z Q1 If you're moving along any path from Q0 to Q1, 3 this thing will change continuously from 11 to 3.

,如果你从Q0沿任意一条路径移动到，值将连续地由11变到。
