I still will need a mathematical formula that can extract the value of each currency from the currency pairs.

Take these previously mentioned pairs as an example

eud/usd=a

usd/cad=b

eur/cad=c

Can we calculate the value of the eur and the cad and the usd at these a,b,c price levels?

Here the equations are rearranged:

eur=a*usd

usd=b*cad

eur=c*cad

Three unknowns and 3 equations. when i solve for any of eur or cad or usd, the result is nonsensical. So, is there another way to find usd, eur and cad?
