Best ResponseYou've already chosen the best response.2tht is very confusing to me, wht happened to the fractions?

Best ResponseYou've already chosen the best response.1first 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

Best ResponseYou've already chosen the best response.1I trust you can take it from there?

Best ResponseYou've already chosen the best response.2I got (5)/(5x25)=(5)/(5x25)

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

wolfgirl

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

Best ResponseYou've already chosen the best response.1no, draw and show me. I don't understand what you just said.

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

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

Best ResponseYou've already chosen the best response.0wolfgirl, 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

Best ResponseYou've already chosen the best response.1no mfleisch5, x=10 is not the correct answer.

Best ResponseYou've already chosen the best response.1\[\frac{4}{x5} = \frac{4}{x5} \times \frac{5}{5} = \frac{20}{5(x5)}\]

dhatraditya

Best ResponseYou've already chosen the best response.1similarly, \[\frac{1}{5} = \frac{1}{5} \times \frac{x5}{x5} = \frac{(x5)}{5(x5)}\]

Best ResponseYou've already chosen the best response.0exactly. and then u multiply the other one by x5

dhatraditya

Best ResponseYou've already chosen the best response.1so, \[\frac{4}{x5}  \frac{1}{5} = \frac{20}{5(x5)}  \frac{x5}{5(x5)} = \frac{20(x5)}{5(x5)}\]

mfleisch5

Best ResponseYou've already chosen the best response.0no, because everything has 5(x5) so u can take all of the denominators out

dhatraditya

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

dhatraditya

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

dhatraditya

Best ResponseYou've already chosen the best response.1that means \[\frac{25x}{5(x5)} = \frac{5}{5(x5)}\]

mfleisch5

Best ResponseYou've already chosen the best response.0if 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

dhatraditya

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

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

Best ResponseYou've already chosen the best response.1also, 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.

dhatraditya

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

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