Question

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

x = __________________ Write your answer as a fraction in simplest form. Use the "/" symbol for the fraction bar.

Answer 1

halp

Answer 2

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

Answer 3

I guess, it says solve for x

Answer 4

i know solve for x, but we need to get the equations right first

Answer 5

oh right lol, sorry im like so out of it when it comes to math
Its
x=4/5 x + 4/3 = 2x

Answer 6

the x is separate

Answer 7

ok lets multiply by 3 on both sides to remove the denominator on the 4/3

Answer 8

\[(3)\frac{ 4 }{ 5x } + (3) \frac{ 4 }{ 3 } = (3)2x\]

Answer 9

2.4 x + 4 =6x
is that right?

Answer 10

where did you get the 2.4x?

Answer 11

3 times 4/5

Answer 12

its 3 times 4/5x

Answer 13

12/5x you cant just pull the x out

Answer 14

i told you that the x was separate though

Answer 15

\[\frac{ 4 }{ 5 }x\]

Answer 16

like this?

Answer 17

ye

Answer 18

\[2.4x + 4 = 2x\] now minus 2x from both sides

Answer 19

0.4x + 2x

Answer 20

or
0.4 + 2x = 2x

Answer 21

\[2.4x + 4 -2x = 2x - 2x\]

Answer 22

so would 2x -2x or just 2x be the answer..?

Answer 23

solve that chunk first

Answer 24

2x-2x is definitely 0

Answer 25

XD ye ik
i got 4.4?

Answer 26

2.4x-2x =?

Answer 27

well that would be 0.4 but i added the 4 cuz u said it up there

Answer 28

its 2.4x + 4

Answer 29

not 2.4x +4x

Answer 30

you can't add the variables and the constants together

Answer 31

ok then 6.4?

Answer 32

"you can't add the variables and the constants together
"
leave it as 2.4x + 4

Answer 33

2.4x + 4

Answer 34

2.4 is a coefficient not a constant term

Answer 35

so we now have \[0.4x + 4 = 0\]

Answer 36

so that would be the final answer?

Answer 37

ick decimals... I would multiply the whole equation by 10 and then solve for x

Answer 38

yes multiply by 10

Answer 39

decimals are evil. we use multiplication to modify the equation and make life easier.

Answer 40

hint: calculator doesn't care about decimals

Answer 41

waddaya got?

Answer 42

ghostbusters.

Answer 43

you seen the goat balls yet?

Answer 44

ya ._,

Answer 45

lel

Answer 46

Um...so the answer is..0.4x + 4 = 0 also, goat...wtf...

Answer 47

correct?

Answer 48

gotta solve for x =_= that's just an equation

Answer 49

thats not your final answer

Answer 50

show it to him if he didn't finish it in 10mins

Answer 51

k/

Answer 52

so first we multiply the entire equation by 10 because dealing with decimals (especially by hand) is torture
0.4x + 4 = 0
(10)(0.4x)+4(10)=0(10)
4x+40=0
now we need x by itself. We don't want that 40 on the left side, so subtract 40 on both sides

finally divide both sides by 4

Answer 53

\[4x + 40 =0\]\[x + 10 -10 = 0 - 10\]
