Question What does substitute mean in this context?

I was reading a book about special relativity when I saw this blok:


(1) $\displaystyle s^2 = \Delta x_1^2 + \Delta x_2^2 + \Delta x_3^2$

My problem is the substitution of (2a).

I don't understand how this substitution looks like or how it works.
This question might be stupid or in the wrong forum, but I really need help.
