Hi, my name is Charles, and I am one of the math teachers from the Maxim Workshop. I'm just going to now teach you how to do some math. Hi, I'm going to show you how to solve equations with variables on both sides. Alright, the first thing we want to do is to set up our basic equation. Now, we've got X plus one equals, and on our right-hand side, we've got two X plus four. The first thing I would do is to bring all the X's to one side and then all the numbers to the other side. Okay, so looking at our X's here, we've got two X's here, and we've got one X here, so it would be easier to take that one X over to the other side. Now if you look at this X, it's a positive X. So as soon as we take it on the other side of the equal sign, it's going to be a negative X. So our equation should look like this now. Minus X and then plus four. Now, if we look at this number here, we want to take it to the other side onto our left-hand side. So, it's a positive there. As soon as we take it to the other side, it's going to do the opposite operation, which is subtract. So we've got one, take away four, equals two X, minus X. Now, all we need to do now is simplify to solve for X. If you take a look at this, you've got one take away four, that would be negative three. And then on the right-hand side, you've got two X's minus one X, similar to two apples, take away one apple, so it's just one apple. Therefore one X. And we just put one X. So, our solution is X equals minus three. And that's how to solve equations with variables on both sides.
