Answer: How to use solver to solve for 2 unknown in a linear equation?
Hi Mike,
You can definitely use Solver in Excel to solve for two unknowns in a linear equation. Here's how you can do it:
That's it! Solver will give you the values of x and y that satisfy both equations. If you have any other questions, feel free to ask.

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 In article , Mike wrote: How to use Excel to solve for 2 unknown in linear equation, for eg, x + Y = 1 3x + 4Y =7 Thanks Mike

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"?  R. Khoshravan Please click "Yes" if it is helpful.

No, Goal Seek is not the same as Solver.
Solver is an addin. It has to be activated: ToolsAddins, check Solver  Kind regards, Niek Otten Microsoft MVP  Excel "Khoshravan" wrote in message ... Solver. Does it mean "Goal Seak" in Excel 2003?

Thanks. After adding will it appear in Tools menu or elsewhere? I added but
it didn't appear in tools menu.  R. Khoshravan Please click "Yes" if it is helpful. "Niek Otten" wrote: No, Goal Seek is not the same as Solver. Solver is an addin.

How to use solver to solve for 2 unknown in a linear equation?
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.

Why not clear the target cell and use two constraints:
C1=1 D1=7 It really is the best way  I have a worksheet to demo this if interested best wishes  Bernard V Liengme Microsoft Excel MVP http://people.stfx.ca/bliengme remove caps from email "JE McGimpsey" wrote in message ...
