Finding all solutions?

In attached there is a system of two nonlinear equations. Graph indicates there are two solutions but Find only finds one of them.

Is there a best practice procedure for searching for other solutions? Maybe by creating a simple program to loop over the x domain (valid values of x) or what do you recommend?

Kind regards,

Michael

For correct solution:

1 .Guess values vectors should be placed before the solve block (why?)

2. The solution should be vectorized.

Sorry, it is an error of Mathcad 15 and Prime too

I remember in Mathcad 11 all was OK with guess values as Viktor, pardon, vector!
