I installed (Add) the solver and solved the set of 2 equations by the method
mentioned by JE McGimpsey. A very nice solution and I was unaware of
handling of set of eq. by excel.
In an extension to above question, is it possible to solve let say a set of
5 equations with 5 unknowns by the same method of JE McGimpsey ? What is the
limit of solver for handling such set of eq.

No, Goal Seek is not the same as Solver.
Solver is an add-in. It has to be activated: ToolsAdd-ins, check Solver

Solver. Does it mean "Goal Seak" in Excel 2003?
XL2003 does not have the "Subject to the Constraints": $C$1 = 1
Where is the "Subject to the Constraints"?

One way:

A1: 1
B1: 1
C1: =A1 + B1
D1: =3*A1 + 4*B1


Set Target Cell = D1
Equal to Value of 7
By changing cells: A1:B1
Subject to the Constraints: $C$1 = 1
