  • Subtitles section
  • Where we left off, we were trying our very best to get to the castle and save whomever we were needing to save.
  • But we had to cross the bridge and the troll gave us these clues because we had no money in our pocket.
  • And if we don't solve his riddle, he's going to push us into the water.
  • So we are under pressure.
  • And at least we made some headway in the last video.
  • We were able to represent his clues mathematically as a system of equations.
  • What I want to do in this video is think about whether we can solve for this system of equations.
  • And you'll see that there are many ways of solving a system of equations.
  • But this time I want to do it visually.
  • Because at least in my mind, it helps really get the intuition of what these things are saying.
  • So let's draw some axes over here.
  • Let's draw an f-axis.
  • That's the number of fives that I have.
  • And let's draw a t-axis.
  • That is the number of tens I have.
  • And let's say that this right over here is 500 tens.
  • That is 1,000 tens.
  • And let's say this is-- oh, sorry, that's 500 fives.
  • That's 1,000 fives.
  • This is 500 tens, And this is 1,000 tens.
  • So let's think about all of the combinations of f's and t's that satisfy this first equation.
  • If we have no tens, then we're going to have 900 fives.
  • So that looks like it's right about there.
  • So that's the point 0 tens, 900 fives.
  • But what if went the other way?
  • If we have no fives, we're going to have 900 tens.
  • So that's going to be the point 900 tens, 0 fives.
  • So all the combinations of f's and t's that satisfy this are going to be on this line right over there.
  • And I'll just draw a dotted line just because it's easier for me to draw it straight.
  • So that represents all the f's and t's that satisfy the first constraint.
  • Obviously, there's a bunch of them, so we don't know which is the one that is actually what the troll has.
  • But lucky for us, we have a second constraint-- this one right over here.
  • So let's do the same thing.
  • In this constraint, what happens if we have no tens?
  • If tens are 0, then we have 5f is equal to 5,500.
  • Let me do a little table here, because this is a little bit more involved.
  • So for the second equation, tens and fives.
  • If I have no tens, I have 5f is equal to 5,500, f will be 1,100.
  • I must have 1,100 fives.
  • If I have no fives, then this is 0, and I have 10t is equal to 5,500, that means I have 550 tens.
  • So let's plot both at those point.
  • t equals 0, f is 11.
  • That's right about there.
  • So that is 0.
  • 1,100 is on the line that represents this equation.
  • And that when f is 0, t is 550.
  • So let's see, this is about-- this would be 6, 7, 8, 9, so 550 is going to be right over here.
  • So that is the point 550 comma 0.
  • And all of these points-- let me try to draw a straight line again.
  • I could do a better job than that.
  • So all of these points are the points-- let me try one more time.
  • We want to get this right.
  • We don't want to get pushed into the water by the troll.
  • So there you go.
  • That looks pretty good.
  • So every point on this blue line represents an ft combination that satisfies the second constraint.
  • So what is an f and t, or number of fives and number of tens that satisfy both constraints?
  • Well, it would be a point that is sitting on both of the lines.
  • And what is a point that is sitting on both of the lines?
  • Well, that's where they intersect.
  • This point right over here is clearly on the blue line and is clearly on the yellow line.
  • And what we can do is, if we drew this graph really, really precisely, we could see how many fives that is and how many tens that is.
  • And if you look at it, if you look at very precisely, and actually I encourage you to graph it very precisely and come up with how many fives and how many tens that is.
  • Well, when we do it right over here, I'm going to eyeball it.
  • If we look at it right over here, it looks like we have about 700 fives, and it looks like we have about 200 tens.
  • And this is based on my really rough graph.
  • But let's see if that worked.
  • 700 plus 200 is equal to 900.
  • And if I have 700 fives-- let me write this down.
  • 5 times 700 is going to be the value of the fives, which is $3,500.
  • And then 10 plus 10 times 200, which is $2,000, $2,000 is the value of the 10s.
  • And if you add up the two values, you indeed get to $ 5,500 So this looks right.
  • And so we can tell the troll-- Troll!
  • I know!
  • I know how many $5 and $10 bills you.
  • You have 700 $5 bills, and you have 200 $10 bills.
  • The troll is impressed, and he lets you cross the bridge to be the hero or heroine of this fantasy adventure.
