It is unsolvable with only elementary algebra, you would have to go beyond that.

anonymous · Answer

The answer is 1 but I want to know the intermediate steps

What are you referring to?

geerky42 · Answer

I mean to solve it, you would have to use some advanced math

So to know that x = 1, you would just have to observe that at x=1, $x^3 = 1$ and $2^{1-x} = 2^{1-1} = 2^0 = 1$

OK, thanks anyways since it seems that it's really too complicated to even explain, I;m in calculus if that helps xD

geerky42 · Answer

yeah, well, you could solve with calculus, probably, but steps is so complicated I cannot comprehend it. You would need to use Lambert W-Function to solve that: http://mathworld.wolfram.com/LambertW-Function.html
