Hello everyone! I've already tried to solve in a block, it seems that something is missing, I'm waiting for your solutions, a lot of thanks

One possible and quick solution would be without units of measurement:

Note that you need only three guess values, when solving for three variables. (Delta, h and R).

The values for X.A,B,C & Y.A,B and C are 'knowns', and can be placed above (outside of) the solve block.

 

Success!
