That makes sense if you think about this process of cell multiplication, that I have one cell it becomes 2 cells in a minute, it could become 4 cells in another minute, it could become 8 cells in another minute and that's all that this set of equations is representing.

如果你和细胞增殖的过程联系起来的话,这个是说的通的,我有一个细胞在一分钟里变成了两个细胞,那就可以再花一分钟变成四个细胞,再花一分钟就变成八个细胞,这就是这个方程所代表的意义

So what we're going to do is take the equations for those two lines, so here's one of those equations and here's the other one, set the P in those equations equal to X, I've got two equations in one unknown, I'm sorry, I've got one equation and one unknown.

接下来我们只需要,列出这两条线各自的方程,也就是这个方程和这个方程,把方程中的P换成X,我就得到了两个等式和一个未知数,错了,是一个等式和一个未知数
