#### Solution Preview

Please refer to the attachment.

To simplify problem, let:

--- = x , --- = y , --- = z

Therefore,

x z + y e [- (z + y) S]

Cr = 1 - ------- -----------------------

x + y z + y

x + y z + y e [- (z + y) S]

[1 - Cr] -------- = -------------------------

x z + ...

#### Solution Summary

This shows how to rearrange an equation to isolate a given variable. The isolating variables are analyzed.
