它们相交于一点，这且是方程的解， 但是或许你能看到，这张坐标图看出来有点难度。

They do meet in one point and that the solution, but maybe you can see that this row picture is getting a little hard see.

这种情况必然发生在,不可逆线性方程组的情况，且等号右边为零。

So, you must be in this case if you have a noninvertible system where the right hand side is zero.

当你使用自动布局时，目标是提供一系列的方程式，而这些方程式有且只有一种解决方法。

When using Auto Layout, the goal is to provide a series of equations that have one and only one possible solution.
