Answer by Fombitz(32388) (Show Source): You can put this solution on YOUR website!
You can get a value of each variable in terms of the constants and other variables.
As an example,

From what you write, I'm assuming that's not what you're looking for.
To get a numerical value for 3 variables, you need 3 independent equations that describe the relationships between the three variables.
