i can't help you with algebraic mode.
In rpn is quite straightforward:
1) enter you equation as 'x+y=z' (whatever). Remember the '
2) press ENTER
3) type the name of the equation
4) press STO
DONE!

Pressing VAR you have access to memory. You should see the name of the equation in one of the softkeys. Just press it to recall the equation on the stack.

Anyway, I suggest to read the manual..... ;-)
