Question

Solve for x: 4 over 5 x + 4 over 3 = 2x

Answer 1

Do you mean\[\frac{ 4 }{ 5x }+\frac{ 4 }{ 3 }=2x\]?

Answer 2

or \[\frac{ 4 }{ 5 }x+\frac{ 4 }{ 3 }=2x\]?

Answer 3

that one yup

Answer 4

Which "that"?

Answer 5

the second one XD sorry

Answer 6

Can you help me please?

Answer 7

@3mar ?

Answer 8

Alright subtract \(\ 2x\) from both sides

Answer 9

Can you do that?

Answer 10

\[\frac{ 4 }{ 5 }x+\frac{ 4 }{ 3 }-2x =2x−2x\]

Answer 11

\[\frac{ -6 }{ 5 }x+\frac{ 4 }{ 3 }=0\]

Answer 12

is there another way because that way doesn't seem correct...?

Answer 13

Now try subtracting \(\frac{ 4 }{ 3 }\) from each side

Answer 14

waitt but we're not done yet.

Answer 15

ok

Answer 16

Anyways when we subtract 4 by 3..we need to get rid of that
\[\frac{ -6 }{ 5 }x+\frac{ 4 }{ 3 }-\frac{ 4 }{ 3 }\]
Which would equal \[0-\frac{ 4 }{ 3 }\]

Answer 17

-4/3

Answer 18

Not that's not the answer.

Answer 19

so -6/5x = -4/3

Answer 20

ik I'm just following along

Answer 21

So ^^yes that

At last multiply both sides by \[\frac{ 5 }{ (-6) }\]

Answer 22

@AloneS sorry but i think that there above you need multiply the 2x by 5 not by 3

Answer 23

@AloneS shouldn't i multiply both sides by -6/5?????

Answer 24

just bc. 4/5 is the coeficient of x and not 4/3

Answer 25

\[(\frac{ 5 }{ -6 }) *(\frac{ -6 }{ 5}x)=(\frac{ 5 }{ -6 })*\frac{ -4 }{ 3 }\]

Answer 26

Yes mybad lol

Answer 27

?

Answer 28

This is confusing me

Answer 29

Can someone explain to me a different way please?

Answer 30

4 4
---x + --- = 2x subtract from both sides 4/3 so what will get ?
5 3

Answer 31

Anyways after dividing that you would get \(\frac{ 10 }{ 9 }\)

Answer 32

4/5x = 2x - 4/3

Answer 33

4 4
---x = 2x - --- and now subtract from both sides 2x and will get
5 3

4
---x -2x = - 4/3
5

(4x-10x)/5 = (-4)/3 cross multiply and will get


3(-6x) = -20 so do you can continue it now ?

Answer 34

ok thank you @AloneS i will follow along @jhonyy9 because he is doing it a different way and i need to follow along because i feel like it would be easier for me

Answer 35

how did u get (4x-10x)/5

Answer 36

on the left side there are

4
---x -2x yes ? so make common denominator and will get (4x-10x)/5 yes ?
5

Answer 37

Lol sorreh @OtherWorldly for making it difficult LOL

Alright. (:

Answer 38

y r u putting a minus sign when it is supposed to be " / "

Answer 39

no

where ?

Answer 40

(4x-10x)/5

Answer 41

there is (4x-10x) divide by 5

Answer 42

bc when you make common denominator so multiply the 2x by 5 and will get 10x/5

but there are

4 10x
---x - ----- = (4x-10x)/5 yes ?
5 5

Answer 43

yeah srry i must of gotten lost in the middle

Answer 44

how or why this is easy

Answer 45

so on the left side will get -6x/5

Answer 46

ok

Answer 47

and on the right side what are there ?

Answer 48

-20

Answer 49

?

Answer 50

right ??

Answer 51

no

-4/3

Answer 52

so we have than

-6x -4
---- = ----
5 3

Answer 53

so multiply 5 on both sides right

Answer 54

not just this

cross multiply and what will get ?

Answer 55

-18x= -20 ???

Answer 56

exactly and now ?

Answer 57

9/10

Answer 58

there are

-2*9x = -2*10 so what can you make on the every two sides ?

Answer 59

-18x=-20.....

Answer 60

x= 9/10

Answer 61

what you see there is a common coeficient ?

Answer 62

-2

so divied both sides by -2 and will get ?

Answer 63

9x=10 right ?

Answer 64

yes

Answer 65

so from this how you get the x ?

Answer 66

courage

Answer 67

x= 1.1 ?

Answer 68

how you ve got this ?

Answer 69

omg i don't know i divided 10 by 9

Answer 70

i made it into decimal but in fraction form its 10/9 its the same thing

Answer 71

np

this is easy way to solve it

9x = 10 divide both sides by 9 and will get

x = 10/9

Answer 72

ok thank you soooooo much i took up too much of ur time but i appreciate it

anytime just tag me

was my pleasure

hope you understood it right now

good luck

bye bye
