Hiya all...
I'm trying to make a program on the 89 that:
1. Takes something like 3x+c=0 | x=1
2. Solves for c so you get c=-3
3. Displays 3x-3

So far, I have
Code:
Disp solve(3x+c=0 | x=1,c)


Problem is that that displays c=-3, but I want it to display 3x-3. Anyone have any idea how to do it?

And no... the calc doesn't save -3 to the variable c, it saves c = -3 to Ans!

:Disp 3x+c
