New Solve for x

I have a 4th degree equation which I have solved for and obtained x.

Using the solve function along with "assume", I filtered out only the positive answer to the equation.

Mathcad displays my answer, but how do I get it to allow me to actually assign that answer to my variable "x" for use in further calculations?

Thanks for your help!

Actually I think I stumbled on the answer, based somewhat on the info you provided. It is attached.

Yes, That is correct. The example I gave was for a function assignment but it works the same way for a variable assignment.

You need an additoinal numeric assignment. See the attached worksheet.

Helpful, but not quite what I was asking.

I should have attached my worksheet.

I have now attached it. What I need to do is take the solution for the equation (the 13.8552...), assign it to a variable, and continue on, using that solution in further calculations.
