Goal seek function

[Fadwa]

Hi

I've seen one of the cases that been solved https://community.powerbi.com/t5/Desktop/HELP-WITH-DAX-Simulate-Excel-What-If-Analysis-Goal-Seek/m-p...

which is too similar to something I've been struggling with I will use the same letter he used, the difference is that I want my goal always to be zero:

( A * x ) - ( B * x ) = 0  

How its gonna work?

I really appreciate your efforts, It will mean a lot if you know the solution!

Not sure the Algebra works on that one.

(A * x) - (B * x) = 0
x * (A - B) = 0
x = 0 / (A - B)
x = 0

So, x = 0
