Hi Mr. Shorty,

Thanks for your reply. Sorry maybe I wasn't clear with my question. Let's put it this way -

Say A1, A2,A3 etc consists the value of M, W, Icl etc .... and I want the value of x to be represented in A10. Therefore, I put in cell A10 my formula as follows =35.7-0.028*(cellA1 – cellA2)-cellA3....., which is x. I do not know the value of x and need it to be computed. So you see my problem? Both the right hand side and left hand side of the equation has x. I want a solution where maybe the RHS doesn't have x.

I hope I am clearer now.

Thanks!
