Question

Hello guys, I would love it if you could help me! I am currently in 6th grade and there's no one else who can help me with my homework besides well.... You guys! Ok so my 3 maths questions I need help with are -3/9 = -1/2
2x/3=4/5
4a+1=3
Please tell me how to work it out! I'm learning about basic equations! Thanks in general

Answer 1

Are those numbers two equations?
Also I'd like to know exactly how those equations are stated?
Is there an online source you can copy and paste?

Answer 2

Do you have skype or something that I could send a picture? sorry for bothering you!

Answer 3

I don't have Skype
You can attach a picture or text to this topic.

Answer 4

How so, I am on a mobile device! Maybe Facebook? Do you have any sort of social media, if not, it's an equation

Answer 5

I don't want you to go to too much trouble.
Anyway, the equations are:
-3/9 = -1/2
2x/3=4/5
4a+1=3

Do I have that right?

Answer 6

Yes! Thank you!

Answer 7

I'm having a LOT of trouble with Open Study at the moment - it keeps kicking me off

Answer 8

My mistake I meant for the fit's question is 3/a

Answer 9

first*

Answer 10

so it is
-3/a = -1/2

Answer 11

Sure Is!!

Answer 12

Do you know how to begin solving for a ?

Answer 13

At class, I was not taught this as we had a test, yet our teacher assigned us with this.

Answer 14

So I'm kinda..... Clueless...

Answer 15

-3/a = -1/2

We can multiply both sides of the equation by "a" which gives us

-3a/a = -1a/2 which can be neatened into:

-3 = -a/2

Then we can multiply both sides by 2 giving us
-3*2 = -a

Do you see that?

Answer 16

What does the star represent?

Answer 17

Multiply (it means -3 times 2)

Answer 18

So for 3a/a, you cancel the 'a's?

Answer 19

sure it is just like saying 3*2 / 2 equals 3

Answer 20

Ohhhh I get it!!! And answer even matches! Thanks! What about 2x/3 = 4/5?? Is it the exact same method?

Answer 21

Well we still have to finish solving for "a"
-3 * 2 = -a

Answer 22

so -3 * 2 = -6

Answer 23

Yes, -6 = -a
so "a" equals?

Answer 24

6???

Answer 25

Because 2 minuses together equal a positive right?

Answer 26

Actually, the proper way to say it
we multiply both sides by -1 and the equation becomes
6 = a
but yes you got it right !

Answer 27

Thanks!!! I think I've got this question now!

Answer 28

So are we getting onto the next question?

Answer 29

Or not

Answer 30

Okay the other 2 equations are
2x/3=4/5
4a+1=3

Let's try
2x/3=4/5

We can multiply both sides by 3 to get
3*(2x/3) = 3*(4/5)

2x = 12/5

Then we divide both sides by 2
x = 6/5

Answer 31

Oh sorry hah! I can't see whether you are typing or not! Weird glitch

Answer 32

Yeah Open Study is giving me a LOT of trouble at the moment.
Anyway moving on to
4a+1=3

we subtract 1 from both sides

4a = 3 -1
4a = 2

Next we divide both sides by 4
and can you figure what "a" is?

Answer 33

2??

Answer 34

No
4a/4 = 2/4
Does that help?

Answer 35

Ahh yeah it does now!i get it and I've awarded you with a medal for you putting up with how dumb I am. I know, I shouldn't even be asking here, this is for advanced maths so I should probably delete this post after I write down the formulas!

Answer 36

Heck there is always somebody to help anyone else no matter if it is beginning algebra or advanced calculus.
Thatks for the medal and I'm glad I could help you out.
I'd better leave Open Study - it is giving me a LOT of trouble.
