error with Solve App

[mcjtom]

Tim,

Could you elaborate on what Solve Eq. actually does with the variables, when values are provided?

The part I don't understand is storing a value of a named constant in the equation in a variable (e.g. G:=1000) vs. storing it (somewhere) by using the Solve Eg. app page (in which case, how does Solve Eq. app treat the second value actually stored under the variable name, say G)?

Cheers
