Can someone help me to find solution for equations which have specific values. I try determinate model for logged signal that. Please see more attached file.

Thanks in advance

That's what solve blocks are for.

You have just two unknowns to solve for but three equations. This usually has no solution. But you can chose two equations and solve:

Find the file attached. It also includes a solve block with minerr, but Fred was faster with this

Here is a third curvefit approach using Mathcad's "genfit" functon to get the same result as the minerr solve block.
