Solve[Function] 2 quick questions

Hi All,

 

I have 2 quick questions regarding the Solve[Function].

Firstly I wish to use Solve[eqns, {A, B}] on a simple system of equations
with missing variables A & B.

However I wish to constrain the results from Solve ...

1# - For all values of A and B to be positive values.

And

2# - One of the variables, say B, to be a positive integer.

 

Please could someone show me the correct coding for these 2 requirements
with a simple working example in both cases.

 

Many thanks for your help & attention.

Best regards,

Lea Rebanks...
