Is x/(x+4) = 1 or 1/4?

OpenStudy (anonymous):

id say 1/4 but ifdk

OpenStudy (alexandervonhumboldt2):

this cannot be simplified

OpenStudy (anonymous):

Don't the x's cancel out?

OpenStudy (alexandervonhumboldt2):

no

OpenStudy (alexandervonhumboldt2):

we divide by x+4 not x

OpenStudy (alexandervonhumboldt2):

we cannot divide denominator into 2 parts

OpenStudy (anonymous):

Well I have to find x in this equation: \[x(1+\sqrt{5}) = 4\sqrt{5}\]

OpenStudy (anonymous):

Oh, wait. I just realized it's simple.

OpenStudy (anonymous):

You do: \[x=(4\sqrt{5})/(1+\sqrt{5})\]
