It is clear that as we have 6 equations and 8 variables, only 6 of the variables may be unknown for us to be able to solve the equations. This means that values must be given for two of them.
(We may either think of this as reducing the number of unknowns by
replacing two of them by numerical values, or as augmenting
the set of equations by adding another two which have the simple form
Typical options for the specifications are as follows:
