When I simplify your equation, I get -8 = 0. I suppose the algorithm works the same on solvable versus insolvable equations, but the latter makes it harder to test your results!

What you have does not resemble RPN as I understand it.

2 (4x - 8) + 3x = 11x + 1 - 9
LHS: 4 x * 8 - 2 * 3 x * + 
RHS: 11 x * 1 + 9 -
