Question

Can someone help me with this one? I would greatly appreciate it! 8x-3=4x+5

Answer 1

are you solving for x?

Answer 2

Yes.

Answer 3

ok so you need to put like terms together...do you know what that means?

Answer 4

Not really, no.

Answer 5

Putting all the x's in one side and the terms without on the other.

Answer 6

ok so you need to put the xs together and the normal numbers together
so subtract 4x from both sides

Answer 7

because whatever you do on one side of the equals sign you have to do to the other.
think of the equals sign as a mirror. every move you make one one side has to be reflected on the other side

Answer 8

I see. So it would be 8x-4x-3=4x-4x+5?

Answer 9

yes exactly and you do the same thing to the normal numbers

Answer 10

So then after that it would be 4x-3=x+5? Or is it just +5 at the end?

Answer 11

Or did I get it absolutely wrong?

Answer 12

you are close but you need to move that 3 over with the 5 because they are like terms
so to move the -3 over you need to ADD 3 to both sides

Answer 13

but we're not done yet! to solve for x we need to get x all by itself

Answer 14

I see.

Answer 15

so what do you have right now?

Answer 16

I'm not entirely sure, but on paper I have; 4x+3=x+5-3+3
I don't know if that's correct...

Answer 17

ok so this is what we have done so far:
8x-3=4x+5
-4x -4x subtract 4x from both sides
4x-3=5
+3 +3 add three on both sides to get rid of the -3
so you should have 4x=8

Answer 18

do you understand this so far?

Answer 19

Yes.

Answer 20

ok so to solve for x we need to get x all by itself right?
So think of 4x as 4 times x
now 4 times x is multiplication so to get x by itself we need to do the OPPOSITE of multiplication which is...?

Answer 21

Division.

Answer 22

yes! so divide 4 from both sides
4x=8
4/4 8/4

Answer 23

what do you get?

Answer 24

You'll have to excuse me if I'm being a bit slow or if I don't follow. English isn't my native language and I've never tried to have a conversation including mathematic terms...

I get 0 and 2, so that means x=2, right?

Answer 25

yes! very good but you should get 1 when you divide 4 by 4
so 1 times x =x
but you wrote it right

Answer 26

Ah, my bad.

Answer 27

what is your native language?

Answer 28

Norwegian.

Answer 29

is that any close to german?

Answer 30

They are related, yes.

Answer 31

well your english is very good and if you need any more help just let me know

Answer 32

Thank you, and thank you so much for your time, you really helped me alot!
