Something like this (knocked up in the Microsoft Equation Editor). I still want Maple to do the math, but to hide what it does at each step.
So, for example, I issue a command for Maple to multiply both sides by 7*x at the first step, but I want to hide this fact.
It occurred to me to firstly create a variable (e.g. eqn) to store the equation, then perform each step on eqn. This didn't work, as I didn't know how to manipulate the document so as to hide the input and show the output. Furthermore, I wasnt able to line up the equal signs.
Then, I thought of creating a table with 3 columns and as many rows as necessary, and with zero borders. I could put the LHS in the first column's cell, put an equal sign in the middle column's cell, and the RHS in the right column's cell. This had the effect of aligning the equal sign (if I center-justify). The problems are twofold here : (i) how to issue a command to the cells in the first and third columns simultaneously; and (ii) as before, how to hide the input.
So, I'm looking for a more elegant solution but I'm up against a brick wall.
