Entered the exact same equation on the line below and it solved it right away. Tried it with the original again (not changing anything) and it solved it too.

Again this sounds like there was an invalid value stored in the variable you solved for. Remember: you always enter TWO guesses! That's the one in stack register X and the one in the variable you solve for.

Dieter, thanks, but I clearly stated in the portion you quoted, that I had cleared all variables.
