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?
@Ms-Brains , what they mean is that you have to subtract 1 from each side of the equation. :P
So it would be B then? or it could be C ..?
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? :)
Subtract 1 from both sides. Sorry I was called away. @YoungStudier
Yes so now it would be: 3x = 2y - 1 What should we do next to get -1 alone on one side?
Divide both sides by three?
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?
Add 1 to both sides? o.O idk..
Uhm, no. :P We wanna subtract each side by 2y in order to get -1 alone.
It's alright c: You're getting it. So now the equation would be: 3x - 2y = 2y - 2y - 1
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:
Yeah, I understand now. Thanks! I got like 3 more, if you could help?
I can try. c:
Yup ^.^ I literally just learned about this cx So what do you think the answer is?
I think it's B..
But, I never worked on these kind of problems
Uhmmm, you're on the right track. These are relatively simple.
The line intercepts (goes through) an exact point on the coordinate plane, or graph, whichever you prefer :P
Oh, so it would be C. Because the line goes through the -1?
Uhm, yeah it does..... O.o Another wonky question.
I've narrowed it down to either A or C. What do you think it is?
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.
So it would be D then. But I don't understand how it would be that. ;-;
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:
Okay. Thanks. cx
No problem c:
Is there anything else you need help with?
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. ^-^
I gotta refresh my memory on how to do this, the math cast explains it xD One sec.
Ooooh okay, so to find the x intercept we need to turn the y into a 0
So we started with 6x - 4y = -12 Now we have: 6x - 4 * 0 = -12
So we need to simplify to find out what x is..?
Yup ^.^ Following the Order of Operations, we would do the multiplication first with 4 * 0
x -2 I already solved it
Yup, so now we have x
Haha, okay now what? :P
Now we need to use the starting equation again. And this time turn x into 0 so that it is 6*0 - 4y = -12
So that we can find the value of y ^.^
Gimme a sec to solve it
So it's A?
Awesome! Thanks so much. :3
No problem! :3
