Since the output of one industry (steel, for example) serves as an input for another (construction), one cannot solve any equation without solving them all simultaneously.

由于一个行业的产出总是会作为另一个行业的投入，因此除非能同时解出所有的方程，否则你一个也解不出。

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 dependent variable 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。

You could write an equation for a process that you could actually solve.

你写出一个关于进程的方程式能求解。

And while I have long since forgotten how to solve a differential equation, I did learn how to drink responsibly (no tequila shots on an empty stomach).
