equation is

a +b x / c+d x = 3 +4 x / 5+6 x where a,b,c,d are constants

So by comparing can we say that

a=3,b=4,c=5,d=6?

I am not sure as to what are you trying to do. I can also say that by having a = 6, b= 8, c =10 and d = 12 the equation is still satisfied. so pl tell us what exactly do you want to do or find out.

if this equation is always true are those the only solutions?

if yes is there any proof of that? - Oct 25th 2013, 04:40 AMvotanRe: Comparing equations with denominators

They are not the only solutions. See ibdutt's post for a second solution. The complete solution set is a = 3n, b = 4n, c = 5n, and d = 6n where n is any (non-zero) real number.=:

Edit: Also, please use parenthesis when necessary. What you wrote was

which is not what you wanted to say. You needed to write this as

(a + b x)/(c + d x) - Oct 30th 2013, 10:10 AMAaPaRe: Comparing equations with denominators
thanks
