Question

solve 2/x-1 + 4/x = 8/x(x-1)

Answer 1

x(2/x-1+4/x=x(8/x)(x-1)
2-x+4=8x-8
14=7x
x=2

Answer 2

can you explain please

Answer 3

\[\frac{ 2 }{ x-1 }+\frac{ 4 }{ x }=\frac{ 8 }{ x(x+1) }\] like this?

Answer 4

yes like that

Answer 5

\[(\frac{ 2 }{ x-1 }+\frac{ 4 }{ x }=\frac{ 8 }{ (x)(x-1) })x(x-1)\]
like @spiel7 said but it come out a little different then he said

Answer 6

what do you get when you do this?

Answer 7

i saw the equation incorrectly. big teach has the ball. find the lcd and you are home

Answer 8

sorry i dont really get it

Answer 9

common lcd is x(x+1)(x-1)

Answer 10

once you do these it will get rid of all the fractions and you will be able to solve the normal way all we are doing is multippling by all the denomenators

Answer 11

there isn't an x+1 denominator, it's x-1

Answer 12

sorry i missed typed the first ime then. So do not multiply by the x+1 just x and x-1 this will make it a lot easier :)

Answer 13

yyou should get
\[2x+4(x-1)=8\]
do you see how?

Answer 14

yea i get it

Answer 15

cool sorry about the confusion!! :)
So get how to finish the equation

Answer 16

so 2x+ 4x-4=8
move over the 8 then factor

Answer 17

there are no x^2 in here so no factor easy solve

Answer 18

6x-4=8

Answer 19

oh yea yea i dont factor, ok yea sorry got it

Answer 20

np

Answer 21

thanks
