SOURCE: How do I solve an
If you do not have an ALPHA key you probably cannot use variable X. Besides, you are not solving anything here. You are merely adding two quantities. The problem is simple. You have solved countless number of similar examples where you were talking about concrete objects.
In algebra X (or any other letter symbol) is a place holder for any quantity you wish it to be. It could be apples, oranges, what have you. Using this analogy, ask yourself the question: 2 oranges + 8 oranges makes how many oranges. The answer is 10.
You will get the same value if instead of X=oranges, you have X=apples. So there is a universal truth and you state that by using an abstract entity called X.
Thus 2X+8X=10X. and X can stand for anything, anything at all.
