Any help appreciated. I sure this has been asked ad infinitum but I can't find the answer.
I want to use Mathcad to assit my child in algebra. At times, I just want to use it instead of pen and paper, for example.
My child may have to solve this simple problem by isolating "x"
5x-7=9
I just want to write this in mathcad and work through the equality. But of course two(2) problems:
1) x appears outline in red as undefined. I've tried preceding it with x:=x and other ideas but nothing works. In fact, in x:=x, the second x has same problem with red outline and undefined error.
2) the "=" causes the problem to solve (if x is defined i.e. x:=2). The solution 3 would appear on the right side of the "=" and I can't type the nine(9).
Well, I'm sure many have seen this before.
Please help as it would be great to do algebra (solving equations manually) using mathcad using the computer where our work can be saved (and double checked by math cad).
Thank you,
DJ
