Symetrical Component Question

[SwiftTarget]

I've been given positive and zero sequence resistance and reactance (X1, X0, R1, & R0) and need to calculate the X/R for my system. I seem to recall that the formula is X/R=(2)*X1/R1 +X0/R0?

Can anyone confirm, its been a while since I've used symmetrical components and appreciate the help.

I recognize that you are using English and that there are some sort of component values, but some additional narrative would make it easier to get cogent responses

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!
