What is an identity equation? Give an example.

Question

Accepted Answer

Hello Today we are asked to figure out which one of our options is an identity equation. So in order to figure out which one is an identity equation, we're going to have to go through each of our options and simplify them. So let's go ahead and start with option a option A gives us the equation two times the quantity X minus four equal to two x minus eight. In order to simplify this, we need to go ahead and distribute to to the quantity X minus four. Doing so is going to give us two x minus eight equal to two X minus eight. Simplifying this. We can go ahead and add eight to both sides of this equation. Doing so is going to leave us with two X equal to two X. And if we divide both sides of this equation by two, what we are left with is X is equal to X. Now what this is saying is that X is equal to itself. And this is the condition for an identity equation, which means that option A is going to be our solution. So I hope this video helps you in understanding how to figure out what an identity equation is. And I'll go ahead and see you all in the next video
