Do you realize you have to make a system of equations?

You there? :P .

Sorry, yeah I'm here and no.. i dont know what to do at all. /:

First of all do you KNOW what a system of equations is?

Okay, and no..

It's where you work with two equations and different variables.

For example like:
|dw:1356304863230:dw|

ohh ok

Do you understand?

kinda

The idea for a system of equations is to solve for both of the variables.

ohh okkay i get it

So I said:
|dw:1356304949957:dw|

Since you are just learning this we will use substitution.

ok

BTW this is NOT the question. It's just an example.

By substitution I mean that you make one variable in terms of another variable.

Does that make sense?

Yeah

|dw:1356305047829:dw|

Does that make sense?

kiinda

Okay, what is it you don't get? :)

Its just a little confusing hah, but i think i it now.

Are you sure? :) . I got time. I can explain if you really need to :) .

Does that make sense?

Why dont u just use x instead of substituting it with y?

Does that make sense? :) .

yeah, but i just dont understand why you need to substitute x with y instead of just keeping x, x?

Okay, think of it this way. Do you know what x is equal to?

no

We aren't given any values for x at all.

oh

So how would you solve for x unless you get rid of it somehow? :) .

Does that make sense?

Oh i get it nowww

Good! :D .

Okay then. So we have:
|dw:1356305797768:dw|
|dw:1356305817320:dw|

Wait wait!!! That's not the question!!! :P . I just provided an example.

|dw:1356305892765:dw|

Okay.(:

Let the children's ticket's price be x
Let the adult's ticket's price be y.

Do you get that?

Yeah

One second. Can you hold on? I need to actually do this out myself ^_^ .

Do you get that?

Does that make sense?

yeah that makes sense

So can you see a way to make an equation from that?

Let the adult's ticket's price be x
Let the children's ticket's price be y.

56x + 112y = 896 ?

Excellent job!

Can you make an equation from that?

23x + 92y = 552 ? c:

Very good! :) .

So we have:
|dw:1356306963125:dw|

Now, we don't what any of the prices are so we have to get rid of one of the variables.

Do you understand? :) .

Now, we don't know*

Yeah i understand.

Now let's pick the first equation. Can you solve for x? :) .

Aww shucks. :P . Thanks for the fanning.

No problem C:

yes, there is going to be a bunch of ugly fractions involved.

It's okay... :) .
|dw:1356307195870:dw|

Now what would you do? :) .

Um..for 56x = 896-112y dive both sides of the equation by 56?

yep :) .

See? You remember just fine :) .

So x equals...? :)

Hah so x = 16 - 112y? i dont think thats right is it?

No :3 .
|dw:1356307670894:dw|

I tend to avoid simplyfing. Don't ask why.

Ohhhhh that makes sense. :P

Now we know what x equals in terms of y.

We have:
|dw:1356307766229:dw|

We know what x equals. Can you substitute for x? :) .

Yes, there is an ugly fraction involved.

I dont know what to do .-.

Okay so we have:|dw:1356308102259:dw|

We know x equals

|dw:1356308121223:dw|

hold on a sec please. I'll brb(:

Substitute for x.

Okay :) .

|dw:1356308143795:dw|
