What number can be decreased by six and the result then doubled to produce 24?

Question

So let us call the number, 'num'. Okay? :D
Now they are asking us to find a number that satisfies all the things that they are saying.
Okay, so what are the things they are saying?

Decreased by 6, so we get: $num~-~6$
This result is doubled, giving us twice the previous answer: $2(num~-~6)$
This equals: 24

So, now we have an equation! ^^
 
The equation is: $2(num~-~6) = 24$

Can you solve this to find, 'num'? :D

Usually,we use something known as a variable in place of 'num', something like a letter from a-z. I don't know why, it just looks neater. Okay, so let 'num' = x [x is thus the 'variable' here]

So the final equation that you have to solve is: 2(x-6) = 24

What do you get? :D
