You can calculate the price of that water.

The one on the left is the Namibian beetle pulling water out of fog.

Here are two organisms that pull water.

So I'm gonna remove a Y, I'm gonna remove Y mass from both sides. Now what will that look like algebraically?

So, it was a pretty big success.

So 3 times 4 is 12.

So to get rid of it, we're going to subtract 16 from both sides of this equation.

If we want to get rid of this 2 here on the left hand side, we could subtract 2 from both sides.

let me just rewrite 20 minus 7y is equal to 6y minus 6.

This is 146 is equal to 180.

So let's get rid of this 3x from the right.

And now we can subtract 2x from both sides.

Now what we can do to solve all of these?

And then we can solve each of these.

Let me solve all of these simultaneously.

But 42 is the same thing as 40 2.

Water is going to be our big, grand challenge quenching thirst.

We go from S to A. If there is a flood, we just try again.

And the best way to do that, we can subtract 22 from both sides.

So I want to get rid of this 2x right over here.

let's subtract it.

So if I subtract, that's minus 18, if I subtract 18 from the right hand side, I also have to do it from the left hand side.

So we don't want this 6x here, so maybe we subtract 6x from both sides.

If Subtraction is Left Associative, then we want to put as many of these parentheses as far to the left as possible.

So we get minus y squared over 4.

And for a swimmer, you need to feel your hands because you need to be able to grab the water and pull it through with you.

But now we know that water is made up of more basic elements.

I just have the minus six here, it's just a negative six now.

That's what we did here.

So this is my equity.

2 x's from the left.

And then there'd be 30 because every time we're picking a card, were using it up.

We also have to change the value of n to keep reducing n as we go.

lately, in the last couple of weeks, people have seen that there's an enzyme called hydrogenase that's able to evolve hydrogen from proton and electrons, and is able to take hydrogen up basically what's happening in a fuel cell, in the anode of a fuel cell and in a reversible fuel cell.

The government thought that this is a very backward area and we should bring a multi million dollar project to bring water from the Himalayas.

If we want the equality to still hold, anything we do to the left hand side of this equation we have to do to the right side of the equation.

Similarly you do the same for C.

Then we only have 29 to pick from.

So first lets add all the y terms

Can you quote a line of Hamlet?

How much of a discount can you give?

So if we start at 5 let me use a different color we start at 5 right here and we're going to go to the left 12 because we're subtracting 12

I'll get 1 is less than or equal to 3X

I subtracted 3X from here

I just swapped them.
