If 10 = 20 and 20=40 then what would 80=

This is poorly phrased since you cannot just reassign values for given numbers.  10=10 and will always equal 10 even if we went to a tribe in africa where 10 is actually written as 15 but that would still equal 15 to them.  

X can be said to equal any number or any letter since in math we know that a letter can equal a number or even a whole function.  

10 =/= 20 but x can equal 10.  

Though from looking at that it looks like a simple 2x equation where X equals the first number so 2x where X equals 80 would be 160.

Two parrots are in front of you along with two doors to the left and right. One door leads to hell and the other leads to heaven. The parrots know which door leads to heaven and which one leads to hell. You get to ask one parrot ONE question to figure out which door leads to heaven.

HOWEVER, one parrot always lies and one parrot always tells the truth. Through asking your one question to either parrot, how can you figure out which door leads to heaven?

I love this one.  You will ask any parrot this question.  "If I would have asked the other question, which door leads to Heaven, what would he say?"

If you asked that to the truth speaking bird you will get a lie since it would have been what the lying bird would have said.  If you ask that to the lying bird he will still tell you a lie since it would be a lie of what the truth bird would say.  So ask them that question then pick the other door.  By asking that question you forced both birds to lie.

It was a hypothetical I know they don't really equal that!!
