Uhm, so what do you need help with? ^u^

The 1 is positive so you have to subtract on both sides.

So what do you think the actual answer would be?

- YoungStudier

@Ms-Brains , what they mean is that you have to subtract 1 from each side of the equation. :P

- Ms-Brains

So it would be B then? or it could be C ..?

- Ms-Brains

@YoungStudier

- YoungStudier

Uhm, no, not quite cx
So let's just look at the equation at the start: 3x + 1 = 2y
What do you think is the first step to solving the equation? :)

- Ms-Brains

Subtract 1 from both sides.
Sorry I was called away.
@YoungStudier

- YoungStudier

Yes so now it would be:
3x = 2y - 1
What should we do next to get -1 alone on one side?

- Ms-Brains

Divide both sides by three?

- YoungStudier

Uhm, no, not quite.
We want to get -1 alone on one side
So what could we do to transfer 2y over to the 3x side?

- Ms-Brains

Add 1 to both sides? o.O idk..

- YoungStudier

Uhm, no. :P
We wanna subtract each side by 2y in order to get -1 alone.

- Ms-Brains

Oh. xc

- YoungStudier

It's alright c: You're getting it.
So now the equation would be: 3x - 2y = 2y - 2y - 1

- YoungStudier

And so that will get rid of 2y on the -1 side
So now the equation is: 3x - 2y = -1
Does that make sense on how we got that? c:

- Ms-Brains

Yeah, I understand now. Thanks!
I got like 3 more, if you could help?

- YoungStudier

I can try. c:

- Ms-Brains

Do you know how to solve these kind of problems?

##### 1 Attachment

- YoungStudier

Yup ^.^ I literally just learned about this cx
So what do you think the answer is?

- Ms-Brains

I think it's B..

- Ms-Brains

But, I never worked on these kind of problems

- YoungStudier

Uhmmm, you're on the right track. These are relatively simple.

- YoungStudier

The line intercepts (goes through) an exact point on the coordinate plane, or graph, whichever you prefer :P

- Ms-Brains

Oh, so it would be C.
Because the line goes through the -1?

- YoungStudier

Uhm, yeah it does..... O.o Another wonky question.

- Ms-Brains

I've narrowed it down to either A or C.
What do you think it is?

- YoungStudier

Uhm, if I remember correctly, the line has to go through the bold black lines with all the numbers labeled on them. And those would we the x and y axis intercepts. So I DON'T think it would be A or C.

- Ms-Brains

So it would be D then. But I don't understand how it would be that. ;-;

- YoungStudier

Yes, D would be correct.
Uhm, I'll PM you a math cast link from my lesson. It's a little different from what you're doing, but it gets the same conclusion in the end and may help you understand this better c:

- Ms-Brains

Okay. Thanks. cx

- YoungStudier

No problem c:

- YoungStudier

Is there anything else you need help with?

- Ms-Brains

Yeah c:
I think it's C.

Uhm, I'm not sure how to explain this one, but try watching the Math Cast as it has a problem similar to this one. ^-^

- Ms-Brains

Okay!. Last one

##### 1 Attachment

- YoungStudier

I gotta refresh my memory on how to do this, the math cast explains it xD One sec.

- YoungStudier

Ooooh okay, so to find the x intercept we need to turn the y into a 0

- YoungStudier

So we started with 6x - 4y = -12
Now we have: 6x - 4 * 0 = -12

- Ms-Brains

So we need to simplify to find out what x is..?

- YoungStudier

Yup ^.^
Following the Order of Operations, we would do the multiplication first with 4 * 0

- Ms-Brains

x -2
I already solved it

- YoungStudier

LOL XD

- YoungStudier

Yup, so now we have x

- Ms-Brains

Haha, okay now what? :P

- YoungStudier

Now we need to use the starting equation again. And this time turn x into 0 so that it is 6*0 - 4y = -12

- YoungStudier

So that we can find the value of y ^.^

- Ms-Brains

Gimme a sec to solve it

- Ms-Brains

y=3

- YoungStudier

Yup! ^.^

- Ms-Brains

So it's A?

- YoungStudier

Yuppers! :D

- Ms-Brains

Awesome! Thanks so much. :3

- YoungStudier

No problem! :3
