When i write wie by itself on google translator, it comes up as as but when i used it in a sentence, it comes up as how. But i do not still understand why the elder person answers back wie geht's? with und wie geht's es. But it has a second use as a comparision particle.

Or if you want to be nice and return the question, gut, danke, und dir/und selbst?. When do you use wie and was in german? Isn't wie geht's = wie geht's (dir)?.
I understand you ask the question with wie instead of was.
Wie is a question word. Wie sieht dein neues auto denn aus? Note however that someone asking you.
