God, Mr. Wood, I'm not getting this.
What do you mean, Nadia?
I don't know, it's just... it's too hard.
You don't understand either of those equations on the board, or...?
Well, I do, but...
Let's come to the board.
We really should have this material by now.
Let's start with this first equation.
This is basic algebra. This is high school algebra.
We're in college now.
2x = 10.
Okay, and then?
Do you want to see how I solve it?
Yeah.
You want to isolate the x, because you want to find out what x is.
Divide both sides by 2.
Which gives you...?
This will give you x, because these will cancel each other out.
x = 5.
Ooh, that was simple.
Simple.
Okay, I get this, but...
Let me see you do this one.
Okay, I guess I'll try.
Okay.
Okay, so I have to isolate the x.
So, I'll subtract 5x on both sides.
Which gives me 3y = -5x + b.
First step, right?
Okay, let me see.
And then, we have to get the y isolated.
So, we divide by 3.
And that gives us y = -5/3x - b/3.
Okay.
I do get it.
See, why don't you apply this on your test, though?
I get nervous.
We have a final in two days here.
Oh no, we do?
Yeah.
I've had it on the course all week.
That's bad.
Well, I guess I'll have to practice more.
I think you'll have to stay after class.
After class?
Yeah, because I don't want you to have to redo the course.
