When i change the value of E in solve block it changes the value of both E and n , but when i change the value of n , nothing happens. Here n and E are two variables i need to find. Other values on left hand side need to be fixed.
If you know any other method to solve, please let me know

dilraj,
Use the symbolic equal sign (Ctrl+=) to define equations within the Solve Block.

Thank you, but could you also explain why the values are changing when i change value of n and e ? is there any other method with which i can get stable answer.
Use please the symbolic solution
Function Find uses numerical methods to solve the system of equations. The solution returned can depend on the guess values.
Here we can find a symbolic solution.

Но там одно решение. И оно не должно зависеть от первого предположения!
Не должно. Но зависит!
You mean the symbolic solver has problems with units. That's why you should use undefined symbols when doing symbolics:
That's close enough to zero.
Success!

The symbolic engine works with 2 variable GPa but the numeric one with 1 variable
And what about тараканьи бега?
