Just stay on the other side of the car.

I'm going to multiply everything by negative 1.

So that's 0.9423.

So you could say 8 x over 13 is equal to 4 fifth times x minus fifteen.

Equals a.

And hopefully you're satisfied with that.

The inverse of that is negative 2.

And so you have this 15 trillions divided by 1.025 or you can divide both sides by 1.025 and multiply both sides by the real GDP.

Mom and Dad?

Both sides, professor.

And now we could square both sides of this equation right here.

And we do the same algebra.

And then let's see, what can we cancel out.

For the velocity of the two trains.

I can say this is going to be x plus something squared.

75 times 5 is 375.

Now, and this is of course in seconds.

He is in a vehicle.

On both sides of the road there are cherry trees.

There are cherry trees on both sides of the street.

And let's see if this actually turns out to be a parabola.

And so we want to figure out what r is.

That does simplify a little bit.

If we take the positive square root.

But anyway, 3x over negative 3.

You don't do anything to the inequality

Our whole goal here is to have a 1 coefficient there.

We could rewrite this as y squared over x squared.

is equal to 6 times Alice's velocity minus 100.

You get 2x is equal to negative 5.

You get 2x is equal to positive 5.

So let me write this.

Who the two sides are?

Get to the vehicle, now! Get going.

And my question to you is

So x minus 1 greater than 0.

This is 146 is equal to 180.

Subtract one from both sides this comes 0.

So let's just do the same step.

You have nine x is equal to eleven.

And now I want to get rid of this negative 5.

'Then the Dormouse shall!' they both cried. 'Wake up, Dormouse!'

These get messy. x minus 1 squared is equal to 16.

And then we can solve each of these.
