Explanation:
what you do on one side, you have to do to the other, for example if the question is x+2=6, you would minus 2 from 2, then minus 2 from 6 which equals 4 so the answer would be x=4. If it was x-2=6 you would plus 2 because it is a negative. If you need any help on any other problems just let me know!
