Answer:

#2x-6#

Explanation:

"Six less than.." means "Subtract 6 from".

Do not confuse this with "Six less..." which means "Subtract from 6".

Confusing, I know.

We know that "Double a number" means #2x#, where #x# is your mystery number.

Therefore, we have:

#2x-6#, which translates to "6 less than 2x" or "6 less than twice a number"
