How would I do this?

inner eagle
#

if a:b=c:d then a/b=c/d

#

therefore 2x-1/x-4=16x+1/2x-1

#

and then cross multiply so (2x-1)^2=(16x+1)(x-4)

#

so 4x^2-4x+1=16x^2-63x-4
12x^2-59x-5=0

#

that looks nasty

#

maybe i did something wrong 1 sec

#

ye its 16x+1 not 16x+4 lol

Ahh okay tysm

inner eagle
#

x=-1/12 or 5

#

also, whenever you have variables in denominators make sure none of your answers make the denominator 0, if they do you just omit that solution

#

but that didnt happen here so youre allg
