Solving for a Variable in 1 step Equations

So, you say you don't know how to do Algebra. Letters in with numbers is dumb, right? 

Well, turns out a variable, usually "x", is just holding the spot for what you're missing.

Meaning  3x = 6 is a sentence that's really saying: Three times "what" is equal to six. 

That's all. Stop thinking so hard about it, and MOST of all, STOP saying letters don't belong with numbers. 

If you hate it that much, then use a question mark every time you don't know something. I, however, would get really sick of making that shape with the dot beneath (?), but that's just me. 

These videos are titled of what they are, so please watch to get a full understanding.
DO NOT just give up. That will never get you what you need, and it's annoying. Thanks.

(Recall your motivational post.)

Videos include details on:
Solving for a variable in 1 step, when it is being multiplied, divided, added or subtracted from. Then there is an extra practice video.

Steps:
1. Figure out what is happening to your variable. (Is it being multiplied, added to, divided by, subtracted from) 

2. Do the opposite operation. (If it's being multiplied, then you divide.etc.)
3. Do the same thing to the other side of the equal sign. 

The videos are separated by operations.

First video - Solving when the variable is being multiplied by something.

Second video - Solving when something is being added to the variable.

Third video - Solving when something is being subtracted from the variable.

Fourth video - Solving when the variable is being divided by something.

Fifth video - All together, do you know what to do?!?
