20(5x25)=5
 3 years ago

mfleisch5 Group TitleBest ResponseYou've already chosen the best response.0
so then (5x25)=25

mfleisch5 Group TitleBest ResponseYou've already chosen the best response.0
then 5x=50 and then x=10 :)

tht is very confusing to me, wht happened to the fractions?

first step: subtract 1/5 from 4/x5 and post what you get. you know how to subtract fractions I assume? take LCM and cross multiply to subtract the LHS expression

for the LHS or RHS?

mfleisch5's answer is incorrect btw.

I trust you can take it from there?

I got (5)/(5x25)=(5)/(5x25)
 3 years ago

dhatraditya Group TitleBest ResponseYou've already chosen the best response.1
how did you get 5/(5x25) on the left hand side of the equation? can you show me the steps?

wolfgirl Group TitleBest ResponseYou've already chosen the best response.2
I multiplied the 5 and the x5, then I thought the 4 was negative and added it with the 1

no, draw and show me. I don't understand what you just said.

dhatraditya Group TitleBest ResponseYou've already chosen the best response.1
first off all, 4 is not negative. secondly, that is not how you subtract fractions.

wolfgirl Group TitleBest ResponseYou've already chosen the best response.2
ok what about (1)/(5(x25)) = (1)/(5(x25))

wolfgirl, all you have to do is multiply 5 and x5. once u do that, you will have all common denominators, so you can cross them out. then you are left with what i gave you, and the answer is x=10

no mfleisch5, x=10 is not the correct answer.

how is it not?

\[\frac{4}{x5} = \frac{4}{x5} \times \frac{5}{5} = \frac{20}{5(x5)}\]
 3 years ago

dhatraditya Group TitleBest ResponseYou've already chosen the best response.1
similarly, \[\frac{1}{5} = \frac{1}{5} \times \frac{x5}{x5} = \frac{(x5)}{5(x5)}\]
 3 years ago

mfleisch5 Group TitleBest ResponseYou've already chosen the best response.0
exactly. and then u multiply the other one by x5
 3 years ago

dhatraditya Group TitleBest ResponseYou've already chosen the best response.1
so, \[\frac{4}{x5}  \frac{1}{5} = \frac{20}{5(x5)}  \frac{x5}{5(x5)} = \frac{20(x5)}{5(x5)}\]
 3 years ago

mfleisch5 Group TitleBest ResponseYou've already chosen the best response.0
no, because everything has 5(x5) so u can take all of the denominators out
 3 years ago

dhatraditya Group TitleBest ResponseYou've already chosen the best response.1
so the left hand side is \[\frac{20x+5}{5(x5)} = \frac{25x}{5(x5)}\]
 3 years ago

dhatraditya Group TitleBest ResponseYou've already chosen the best response.1
now, the right hand side is \[\frac{5}{5x25} = \frac{5}{5(x5)}\]
 3 years ago

dhatraditya Group TitleBest ResponseYou've already chosen the best response.1
that means \[\frac{25x}{5(x5)} = \frac{5}{5(x5)}\]
 3 years ago

mfleisch5 Group TitleBest ResponseYou've already chosen the best response.0
if that is true then that would mean there would be unlimited answers because no matter what u put for x it will work out. u are wrong hatra! its 10
 3 years ago

dhatraditya Group TitleBest ResponseYou've already chosen the best response.1
the denominators are the same on both sides of the equation. that means the numerators are equal too. so, \[25x = 5\] solve for x.
 3 years ago

dhatraditya Group TitleBest ResponseYou've already chosen the best response.1
you get x = 30

dhatraditya Group TitleBest ResponseYou've already chosen the best response.1
got it, wolfgirl? also, mfleisch5, you are still wrong. follow the steps I have shown.

wolfgirl Group TitleBest ResponseYou've already chosen the best response.2
almost, there are a lot of numbers

mfleisch5 Group TitleBest ResponseYou've already chosen the best response.0
no. u are wrong. blah.

dhatraditya Group TitleBest ResponseYou've already chosen the best response.1
ignore mfleisch5, ignore the pictures I drew, just follow the steps I have shown

Let me know if you have any difficulties.

wolfgirl Group TitleBest ResponseYou've already chosen the best response.2
alright I got it thanks :)

also, mfleisch5, substitute 10 in the original equation and see if it is right. its a very easy test to see if your answer is correct or not.
 3 years ago

dhatraditya Group TitleBest ResponseYou've already chosen the best response.1
when you substitute x = 10 in \[\frac{4}{x5}\frac{1}{5} = \frac{5}{5x25} \] you get \[\frac{4}{105}\frac{1}{5} = \frac{5}{5025} \rightarrow \frac{4}{5}\frac{1}{5} = \frac{5}{25}\] \[\frac{3}{5} = \frac{1}{5}\]
 3 years ago

dhatraditya Group TitleBest ResponseYou've already chosen the best response.1
which is a contradiction. therefore x = 10 is not the correct answer.
