Math Problem

puppyloverlauren • 23 October 2012 at 8:32 PM

I need help in a math problem for homework.
Here is the problem:

x+3/5= y

can someone help me?

What does / mean? o3o

@puppyloverlauren

macosten • 23 October 2012 at 8:34 PM

/ means divide.

Now, is 3/5 a fraction or not?

puppyloverlauren • 23 October 2012 at 8:34 PM

@chapus2009

divided by 😸 so it's

x plus 3 divided by 5 equals y and I have to write this problem in a standard form and give the values of A, B, and C.

This is 7th grade math btw!

iceyfira • 23 October 2012 at 8:35 PM

Well, what does "x" equal? 3/5 means 3 divided by 5.

mairbear • 23 October 2012 at 8:35 PM

@puppyloverlauren

Eehh you have 2 variables and 1 equation... I don't think it's solvable.. is there more to the question? o_O

vampire666 • 23 October 2012 at 8:35 PM

@puppyloverlauren - I'm terrible at math, sorry. XP

macosten • 23 October 2012 at 8:36 PM

Seems more like a function to me... Are you sure it's not a linear equation? (What am I thinking, you're the one with the paper... XD)

@puppyloverlauren

puppyloverlauren • 23 October 2012 at 8:37 PM

@iceyfira @mairbear @vampire666 @macosten

yes it is a linear equation XD stupid math

despair • 23 October 2012 at 8:37 PM

@iceyfira They don't have to tell you x's # for you to solve it xD

macosten • 23 October 2012 at 8:38 PM

Oh. Then you need to plug in values for X to get Y.

@puppyloverlauren

iceyfira • 23 October 2012 at 8:38 PM

@despair Dont judge me for being sucky at math.
@puppyloverlauren >.< I dunno. I have similar work... so yeah. llD

puppyloverlauren • 23 October 2012 at 8:38 PM

@despair

yeah *sigh* i hate my teacher, she is horrible and assigns so much homework, she doens't explain well either! Well, she is better at explaining than my last year math teacher ._.

dada_dragon • 23 October 2012 at 8:38 PM

@puppyloverlauren
There must be more to the equation that this, eh?

EDIT:
Oh, it's one of THOSE equations. Never mind. I am no help in this case.

despair • 23 October 2012 at 8:39 PM

I really could solve this, but I'm waaay to lazy xD

puppyloverlauren • 23 October 2012 at 8:39 PM

@dada_dragon @macosten

No ._. the directions say to write each question in a standard form and give the values of A, B, and C. It is a linear equations
._.

macosten • 23 October 2012 at 8:40 PM

There has to be more to this, otherwise it won't be solvable. Try plugging in a value for X and seeing what you'll get. Remember the Order of Operations.

Do A B and C have values?

Linear Equations make lines on a graph. Without an X coordinate, A Y coordinate will be impossible to get, if I'm understanding correctly. I don't think we're getting the whole picture, perhaps at our faults ._.

@puppyloverlauren

Okay. I just finished this in school xD

So.

x+3/5= y

Let's say that x = 1.

1+3/5=1.6

Now, pretend that x is 2.

2+3/5=2.6

X is now 3.

3+3/5=3.6



X can be ANY NUMBER. You just swap x with that number and you solve it.

Do you get it? 3/5 is 0.6, so all you are doing is x+0.6.


EDIT: Never mind. Not sure if this helps xD

macosten • 23 October 2012 at 8:44 PM

@cat That helps, but there was no given value for X, and I think that's tripping us up.

mairbear • 23 October 2012 at 8:44 PM

@puppyloverlauren

Lols... if it's a linear equation then you've got nothing to solve 😋

A = -1
B = 1
C = -3/5

I'm fairly sure that's right... a bit too lazy to double check atm 😋

dada_dragon • 23 October 2012 at 8:45 PM

@puppyloverlauren
I feel your pain... I wish I could be more help but... *pokes edit on last post* ...as you can see, I am unable to assist you on this one... I remember some math, but linear equations was one of those things I wiped from my memory to make room for art history. Lol.

despair • 23 October 2012 at 8:45 PM

EDIT: OH. IT'S LINEAR XDDD NVM😋



I did this xD


I worked backwards so..



y times 5 (as it's the opposite of division) minus 3. I just tried y as 3 so..



3 x 5 = 15
15 - 3 = 12.



So..


x + 3 / 5 = 12

57 + 3 = 60
60 / 5 = 12. 😋





I'm not sure if that's right, depending on the way you have to do it. But, since it wasn't specific, it'd be under my assumption that you'd plug in numbers;)

So, if you were trying to find x, and y, one combo would be:


x = 57
y = 12.


But you're solving for A, B, C. So...*Does more work* xD

cat • 23 October 2012 at 8:45 PM

@macosten Well, yeah xD Lemme add something.

X can be ANY NUMBER. You just swap x with that number and you solve it.

dada_dragon • 23 October 2012 at 8:46 PM

I finished grade 7 eight years ago, so I have had plenty of time to forget. XD

@puppyloverlauren

macosten • 23 October 2012 at 8:47 PM

@mairbear It's not a quadratic, so I don't think it would have an A, B and C term, in that sense. Then again, if they aren't there, they're 0.

mairbear • 23 October 2012 at 8:53 PM

@macosten

The standard form of the equation is

0 = Ax + By + C

You're not solving for either x or y, you just need to state the given constants in the equation.. I'm basing this off what @puppyloverlauren said in an earlier post

twilight_raptor • 23 October 2012 at 8:54 PM

x+3/5= y

The standard form is Ax + By = C (Correct me if I'm wrong)
Where A is the number before x and cannot be negative (like 8x, 4x, etc.) and B is the number before y (like 4y, 2y (not 2+y)) and C is the number on its own (c should be an integer. not fractions or decimals)

so writing it out would give: 5x -5y = -3

Steps:

x+3/5= y
Since x is already positive we'll leave it in its place. We have to remove y from the right and place it on the left (this can be done by adding -y on each side:

x -y +3/5 = y-y
x -y +3/5 =0

C comes on the right and to remove it from the left you can add -3/5 on each side:

x -y =-3/5

C here is a fraction so to make it a whole number you can multiply both sides by 5:

5 (x -y) = -3(5)/5
5x -5y =-15/5
5x -5y =-3

cqpkytty • 23 October 2012 at 8:55 PM

@puppyloverlauren
The standard form of a graph equation is y=mx+b.
😋

EDIT: Oh wait, the OTHER standard form of the equation. 0=Ax+By+C. 😋

@twilightraptor
You mean 0=Ax+By+C. 😋

twilight_raptor • 23 October 2012 at 9:00 PM

@cqpkytty thats the standard for for exponentials right:
Ax^2 + Bx +C=0 something like that? 😋

macosten • 23 October 2012 at 9:02 PM

@mairbear

Most linear equations are in a format like

y=mx+b

Right?

Oh dear, in all of this technical stuff I think we've lost the person we're trying to help...

@twilight_raptor That's for a parabola. 😸 Also, it doesn't equal zero; it equals y.
