Defining variable as an equation?

I must admit that I am a pure MathCad rookie in regards to any of the even only slightly more advanced features. My abilities are limited to Solve, Float and Clear. Even though I can to some extend see what you are doing, I very much doubt that my old-school non-Mathcad trained teacher are going to feel that your solution is more straight forward than just using the "solve" method i described in my file

You are certainly correct in respect to x=5=x+3 makes no sense. But I mean it more like x is defined as 5=x+3. With your method I do not get the benefit of actually defining x. Also I essentially introduce another variable called "Equation", which my teacher might not understand the point of. Also i would have to clear() that variable after each calculation.

General

Understand that my teacher is used to getting handwritten(although calculated with a calculator) solutions to equations in the like of just:

5 = x +3
x = 2

Which is why he is complaining about the "messy state" of my MathCad documents. I appreciate very much your ideas but it is unfortunately not really what I am looking for.

Yes I see your point and agree fully. Mathcad and any other CAS program needs exact instructions to understand what to do. Problem is that my teacher is not happy with the "telling the program what to do" part of the equation(solve, float etc). Your suggestion about solving in Mathcad, but writting on paper is a solution of course but that would defeat the purpose(in my case at least) of using Mathcad. The 2 main reason for me to use Mathcad is firstly to not having to write down equations twice(ones on the calculator and once one the paper) and secondly to use Mathcad ability to remember results(definitions) which is very handy during a series of many equations. At the exams the time limit is really the difficult part. Being able to shave off a minute here and there is a huge advantage.

Ah I see how it works now. Thank you. I will show it to my teacher, but I have a feeling that he wont accept it. From the perspective of an "pen and paper" teacher he most likely will not like MathCad language.

Anyway thanks again guys

I did actually use Mathcad 15 some years ago back at what would in the states probably be equivalent to college. But I must admit that the interface were quite cumbersome, but much worse were that it were so unstable. Countless hours of schoolwork was lost over the years due to random crashes of the program. Also I feel that it would sort be a step backwards to go back to MathCad 15 when Prime has been out for quite some years now?

That is actually a quite neat solution you are proposing there. That would solve my problems without impeding the workflow too much. Only thing is that you can actually see the collapsed area line when printing out. I found an another PTC forum thread that solved that problem:Solved: Hide the "collapsed region" lines when printing a ... - PTC Community

But that must have been in an another version of MathCad or MathCad Prime because I cannot right click on the lines nor can i find any "properties" menu anyway else. Still That could be the solution. I must consult my teacher.
