Some of them are held fixed, and then some dependentvariable does whatever it must so that the constraint keeps holding.
而它们中的一些保持恒定不变，因变量按某种自然的方式变化，从而维持约束条件。

I mean, in the beginning I had this relation that was an equation of degree three. You don't really want to solve your equation for the dependentvariable usually.
我的意思是，在开始有一个关系，这个关系是一个三元方程，一般地，不会为了求因变量而求解一个方程。

Right below the test options, there's a combo box that lets you choose the dependentvariable.
