Two times a first number decreased by a second number is 4. The first number increased by twice the second number is 27. Find the numbers

here is what i have so far:
2x-x=4 ..is that set up wrong? because then it would be 0=2 which wouldn't be a true answer.
and for the second number I am having an even harder time. help please
