Sinplify by adding like terms: 5-x+xy-3yx-2+2x

Start by moving the like terms by each other. I started by moving the whole numbers together like this:
5-2
Next I took the C's and put those together after the whole numbers.
5-2-x+2x
I then took the remaining numbers and put those together on the end.
5-2-x+2x+xy-3xy

Add the like terms together and you get your final answer which equals:
3+x-2xy

820,000 is the answr
