New questions go in new threads.

log_2(x^3) = log_2(6 - x)

x^3 = 6 - x

x^3 + x - 6 = 0

There are no "nice" solutions to this equation, so it isn't surprising that you haven't been able to solve it. Numerically I get x = 1.634365293.

"I must not fear. Fear is the mind killer. Fear is the little death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain." - The Litany Against Fear, "Dune" by Frank Herbert
